For any type of structure, the foundation is very important and it has to be strong to support the entire structure. In order for the strong foundation, the soil around it plays a very critical role. To work on soils, we need to have proper knowledge about their properties and factors which affect their behaviour. By consolidating under load and changing volumetrically along with seasonal moisture variation, these problems are manifested through swelling, shrinkage and unequal settlement. In this paper the experimental results obtained in the laboratory on expansive soils treated with industrial waste fly ash and lime are presented. A study is carried out to check the improvements in the properties of expansive soil with fly ash and lime in varying percentages. The test results such as liquid limit, standard proctor and differential free swelling test obtained on expansive clays mixed at different proportions of lime and fly ash admixture are presented and discussed in this paper. The results show that the stabilized clay has lesser swelling potential whereas an increase in optimum moisture content has been observed. P. Bala Krishana | G.

Overview of Soil Stabilization :Cement / Lime :PPTAniket Pateriya
Soil-cement is frequently used as a construction material for pipe bedding, slope protection, and road construction as a sub-base layer reinforcing and protecting the subgrade. It has good compressive and shear strength, but is brittle and has low tensile strength, so it is prone to forming cracks.
Lime can be used to treat soils to varying degrees, depending upon the objective. The least amount of treatment is used to dry and temporarily modify soils. Such treatment produces a working platform for construction or temporary roads. A greater degree of treatment supported by testing, design, and proper construction techniques--produces permanent structural stabilization of soils.

Experiential Investigation on the Stabilization of Dispersive Soil with Limeijtsrd
The soils that are highly susceptible to erosion and containing high percentage of exchangeable sodium ions are called Dispersive Soils. In appearance, dispersive clays are like normal clays that are stable and somewhat resistant to erosion, but in reality they can be highly erosive and subject to severe damage or failure. Using dispersive clay soils in hydraulic structures, embankment dams, or other structures such as roadway, embankments can cause serious engineering problems if these soils are not stabilized and used appropriately. This problem is worldwide, and structural failures attributed to dispersive soils have occurred in many countries. This paper presents the stabilization of dispersive soil with lime. The soil sample is taken from Mandalay. Grain size distribution, Atterberg's limit test, compaction test, unconfined compressive strength UCS test and triaxial test are carried out to obtain the properties of soil. Type of studied soil classified by unified classification system is lean clay with sand. Crumb test is performed to know the dispersion degree of study soil. According to crumb test, the study soil is highly dispersive clay soil. Lime is used as stabilizing agent. The amount of lime used is 2 , 3 and 4 by dry weight of soil. The studied soil is mixed various contents of lime, and then crumb test is performed. At dispersive soil mixed with 4 of lime, there is no dispersion characteristic in soil. For stabilization of studied soil, 4 of lime is selected to investigate the improvement of strength in treated soil. The treated soil is performed compaction test, unconfined compression strength UCS test and triaxial test. Unconfined compression strength of treated soil at 4 lime is increased as 1.12 times that of natural soil. The shear strength of treated soil increases about 2 times than that of natural soil. The cohesion value of treated soil increases about 1.12 times and the angle of internal friction increases about 1.23 times than that of natural soil. Finally, it is concluded from this study that the lime treated soil is more resistant to erosion and the treated soil is more resistant to shear stress and lateral pressure.

This paper presents study of the stabilization of natural soil with lime. Firstly, Soil samples from Madaya Township are collected and several laboratory tests are carried out to determine the characteristics and engineering properties of the studied soil. Then experimental tests have been conducted for the determination of Atterberg limits and California Bearing Ratio CBR values. The studied soil contains more than 50 of silt clay fraction. So, the studied soil is stabilized with lime contents selected as 5 and 10 by weight of natural soil at maximum dry density. When soil samples are mixed with lime, the values of liquid limit, plasticity index and CBR values are changed. These changes are decreased in swelling and shrinking potential of the soil, decreased in the settlement of the pavements, increase in workability and increase in the bearing capacity of the soils. In this study, the CBR values of soil lime mixtures are 71.4 and 64.4 higher than that of studied soil. It can be seen that the CBR value of lime 5 is greater than lime 10 and natural soil. So, soil lime mixture with lime 5 content is suiTablefor soil stabilization of the street, road and highway.

Expansive soils are produced from the break down of basic igneous rocks where seasonal variation of weather is extreme. In India, these soils are normally derived from the weathering of basalt rocks. Also, these soil deposits are derived from various other types of rocks including very old sedimentary depositsin the present research, an attempt has been made to study the stabilization of the local soils high and low expansive having low bearing strength from two different parts of Bhopal by mixing independently with dolochar and fly ash plentily available in Bhopal in the proportions from 5 up to 30 by dry weight of the mixture with increment of 5 with and without lime The experimental programme conducted in this study is comprised of index tests, compaction tests, shear tests, unconfined compressive strength tests, CBR tests and consolidation tests in conformity with approved standards on soil alone and also on stabilised soils to evaluate their individual swelling, compaction, strength, compressibility and drainage characteristics. With addition of fly ash or dolochar, the L.L. and P.I. of soils gradually decreases with the increase of fly ash or dolochar contents. Maximum decrease is observed at 30 fly ash or 30 dolochar content Addition of fly ash or dolochar decreases the free swell index FSI of soil, maximum decrease being observed at fly ash or dolochar content of 30 . Addition of lime to the above mixtures, reduces FSI further. The FSI of soil 1 with 30 fly ash or dolochar content is reduced by 100 and 85 for soil fly ash and soil dolochar mixture respectively at 4 lime content. CBR of soil fly ash or soil dolochar increases with the increase of fly ash or dolochar content. The maximum increase being observed at 30 fly ash or dolochar content. At 30 fly ash content, the 4 days soaked CBR of soil 1 and soil 2 increase by 126 and 117 respectively, whereas, the 4 days soaked CBR of soil 1 and soil 2 at 30 dolochar content increase by 154 and 163 respectively.

Pavement engineers have long recognized the long term benefits of improving the strength and durability of pavement soil by mixing in a cementitious binder during reconstruction or new construction. In lieu of these, this research was carried out to study the effects of coconut waste ash CWA on lime stabilized lateritic soil for road construction. Natural lateritic soil was collected from a borrow pit nearer location Preliminary tests such as natural moisture content, specific gravity, particle size distribution and Atterberg limits were carried out on the soil for classification and identification purposes according to BS 1377 part 2 1990 . Strength tests such as compaction, California bearing ratio and unconfined bearing ratio were also carried out on the natural lateritic soil and stabilized soil according to BS 1924 1990 . The soil sample was mixed with lime in the proportions of 2, 4, 6, 8 and 10 , and were each subjected to Atterberg limits tests and strengths to determine the optimum quantity of lime for stabilizing soil. The plastic index varied from 13.93 – 9.33 and 23.64 – 14.46 for lime stabilized soils with optimum values obtained at 8 and 6 respectively. Plastic index decreased as the percentages of lime and CWA increased for CWA of ratio 1 1, 3 2 and 2 3 i.e. PI varied from 8.63 to 11.91 . Notable improvements were also observed in the MDD, UCS, OMC and CBR values of stabilized soil therefore coconut waste ash can be used to stabilize lateritic soil.

An Experimental Study on Stabilisation of Loose Soil by Using Sisal Fiberijtsrd
Soil Properties which creates a crucial impact on construction activities due to the rapid growth of urbanization and industrialization. Especially in expansive soils are creating worldwide problematic soil these having large volumetric change behavior when it undergoes a change in the moisture content. Among those, black cotton soil are one type of expansive soils and they show high swelling and shrinkage behavior owing to fluctuating water content. In India, black cotton soil covers as high as 20 of the total land area and majorly in central and south India. If it should be used as foundation material, Improvement of soil need to be done by adopting various techniques like soil stabilization, reinforcement etc. Usage of locally available admixtures is effective in terms of easy adaptability and economy.The main objective of this study is to assess the possibility of using sisal fiber as a stabilizing agent and to understand the effectiveness of sisal fibers in controlling several properties of black cotton soil under controlled laboratory conditions. To achieve this goal several experimental studies like optimum moisture content, compressive strengths tests UCS , CBR, etc., were carried out with the addition of different percentages of sisal in black cotton soil sample as trial and error process. In the present study, the soil samples prepared with the addition of sisal fibers by 0.25 , 0.5 , 0.75 , and 1 the average length of sisal fiber is going to use in this study is approximately 10 15mm.

A Study on Utilization of Admixtures for the Stabilization of Swelling Soilsijtsrd
Rapid urbanization along with the development of large scale industries has created numerous environmental problems. With the reduction of buildable ground, the construction sector has to move to areas with clay soil for expansion, which require soil stabilization. Any construction work over subgrade clay soil is expensive since treatment with various admixtures is required. Civil engineers, structural engineers, architects, and builders have tried many ways to avoid the damaging effects of expansive soils. This study shows that admixtures help reduce the costs of construction on expansive soil as well as the disposal of industrial wastes. Technological advances have made it possible to introduce new technologies in civil engineering for instance, geosynthetics are embedded in the soil to reduce the height of replacement soil. The purpose of this study is to critically evaluate the methodologies for improving the geotechnical properties of clay soil. Three different types of soils were collected from Bhopal M.P. . Based on their physical chemical parameters, these were classified as Low Compressibility of soil CL , Medium Compresibility of soil CI , and High Compressibility of soil CH according to IS standards, respectively. The different admixtures QD, MP, and FA, which are abundantly available in quarries and thermal industries, were collected and their physical and engineering properties were determined. Three soil samples were mixed with the admixtures at different ratios and their maximum dry density and optimum moisture content were determined. The trials were conducted with the addition of admixtures ranging from 10 to 40 by weight to Soil 1, Soil2, and Soil 3, and the dry density was obtained. The experimental results showed that the dry strength of Soil 1 QD 70 30 is higher than that of Soil 1 with other admixtures of different ratios. The experimental results showed that the dry strength of Soil 2 QD 70 30 is higher than that of Soil 2 with other admixtures of different ratios. The experimental results showed that the dry strength of Soil 3 QD 80 20 is higher than that of Soil 3 with other admixtures of different ratios. Regarding the Optimum Moisture Content OMC , the variations in OMC for Soil 1, Soil 2, and Soil 3 are 21 , 24 , and 26 , respectively. Soil 3 has greater OMC to achieve the corresponding Maximum dry density MDD . Water was adsorbed on clay minerals based on the percentage of clay content. Since Soil 3 has higher clay content, the OMC was higher to attain the MDD. From the test results, the best soil and admixture with the best ratio was identified. The best admixture QD was mixed with soil samples, but the proportion was reduced. Then, experiments were carried out by introducing single and double layer geogrid. The swell behaviour of soil, the time settlement, swell pressure, load settlement, and California bearing ratio CBR of the soil with QD at the best reduced ratio were analyzed. The swelling values controlled by t
Characterization of Red Mud as a Construction Materials Using with Natural Soilijtsrd
Soil is very important in civil engineering constructions. The poor engineering properties of the local soils may present many difficulties for construction and therefore need to improve their engineering properties. Stabilization techniques can be used to improve the properties of soil.

Utilization of Bamboo Fibers for Modification of Black Cotton Soil Propertiesijtsrd
Soil stabilization is the process which involves enhancing the physical properties of the soil in order to improve its strength, durability etc. by blending or mixing with additives. The different types of method used for soil stabilization are Soil stabilization with cement, Soil stabilization with lime, Soil stabilization using bitumen, Chemical stabilization and a new emerging technology of stabilization by Geo textiles and Geo synthetic fibers. In this study, we are making use of bamboo fibers as geo synthetic material for stabilization of soil. With the introduction of bamboo fibers to the soil the CBR values will improve and thickness of pavement layer also gets reduced. It also reduces the intensity of stress on subgrade. Bamboo fibers is such a geosynthetic material which is easily available, ecofriendly and also cost effective. With the application of soil stabilization method in construction the overall cost gets reduced when compared to the ordinary method of construction. The Highway Research Board HRB classification of the soil strata like black cotton soil and sedu soil is done using suitable sampling technique such as Core Cutter Method. To determine the characteristics like Grading by Sieve Analysis, Atterbergs Limits i.e Liquid limit using Cone Penetration Method and Casagrande Method, Plastic limit by rolling the sample to 3mm diameter thread, Shrinkage limit using Shrinkage apparatus, Optimum Moisture Content and Maximum Dry Density using Standard Proctor Test and also California Bearing Ratio by conducting CBR test.

Efficient Way to Improve Subgrade Property of Pavement by Chemical StabilizationIJERA Editor
There are numerous soil stabilization techniques for improving the strength of the in-situ soil especially in road construction, and one of the techniques is using chemical additive. Chemical improvement is a time saving method that enables subgrade or sub-base layer and otherwise unsatisfactory materials in-situ to obtain higher density and strength, obviating the need for costly excavation and replacement with borrow material. This paper presents some results of the preliminary stages of research program carried out to explicate the mechanism and behavior between the liquid chemical and the engineering properties of three natural residual soils at laboratory scale. Liquid-formed chemical was selected in this research due to scarcity of such findings instead of the prevalent solid chemical additive such as lime, cement or fly ash. The focus on this research is on the improvement of engineering properties of two natural residual soils and mixed with different proportions of liquid chemical. Series of laboratory test on engineering properties, such as Modified Proctor Test, Consistency limits, moisture-density relationship (compaction) and California Bearing Ratio was undertaken to evaluate the effectiveness and performances of this chemical as soil stabilizing agent.

The Impact of Digital Media on the Decentralization of Power and the Erosion ...ijtsrd
The impact of digital media on the distribution of power and the weakening of traditional gatekeepers has gained considerable attention in recent years. The adoption of digital technologies and the internet has resulted in declining influence and power for traditional gatekeepers such as publishing houses and news organizations. Simultaneously, digital media has facilitated the emergence of new voices and players in the media industry. Digital medias impact on power decentralization and gatekeeper erosion is visible in several ways. One significant aspect is the democratization of information, which enables anyone with an internet connection to publish and share content globally, leading to citizen journalism and bypassing traditional gatekeepers. Another aspect is the disruption of conventional media industry business models, as traditional organizations struggle to adjust to the decrease in advertising revenue and the rise of digital platforms. Alternative business models, such as subscription models and crowdfunding, have become more prevalent, leading to the emergence of new players. Overall, the impact of digital media on the distribution of power and the weakening of traditional gatekeepers has brought about significant changes in the media landscape and the way information is shared. Further research is required to fully comprehend the implications of these changes and their impact on society.

The Role of Mentoring and Its Influence on the Effectiveness of the Teaching ...ijtsrd
This paper reports on a study which was conducted to investigate the role of mentoring and its influence on the effectiveness of the teaching of Physics in secondary schools in the South West Region of Cameroon. The study adopted the convergent parallel mixed methods design, focusing on respondents in secondary schools in the South West Region of Cameroon. Both quantitative and qualitative data were collected, analysed separately, and the results were compared to see if the findings confirm or disconfirm each other. The quantitative analysis found that majority of the respondents 72 of Physics teachers affirmed that they had more experienced colleagues as mentors to help build their confidence, improve their teaching, and help them improve their effectiveness and efficiency in guiding learners’ achievements. Only 28 of the respondents disagreed with these statements. With majority respondents 72 agreeing with the statements, it implies that in most secondary schools, experienced Physics teachers act as mentors to build teachers’ confidence in teaching and improving students’ learning. The interview qualitative data analysis summarized how secondary school Principals use meetings with mentors and mentees to promote mentorship in the school milieu. This has helped strengthen teachers’ classroom practices in secondary schools in the South West Region of Cameroon. With the results confirming each other, the study recommends that mentoring should focus on helping teachers employ social interactions and instructional practices feedback and clarity in teaching that have direct measurable impact on students’ learning achievements.

This study primarily focuses on the design of a high side buck converter using an Arduino microcontroller. The converter is specifically intended for use in DC DC applications, particularly in standalone solar PV systems where the PV output voltage exceeds the load or battery voltage. To evaluate the performance of the converter, simulation experiments are conducted using Proteus Software. These simulations provide insights into the input and output voltages, currents, powers, and efficiency under different state of charge SoC conditions of a 12V,70Ah rechargeable lead acid battery. Additionally, the hardware design of the converter is implemented, and practical data is collected through operation, monitoring, and recording. By comparing the simulation results with the practical results, the efficiency and performance of the designed converter are assessed. The findings indicate that while the buck converter is suitable for practical use in standalone PV systems, its efficiency is compromised due to a lower output current.

Sustainable Energy by Paul A. Adekunte | Matthew N. O. Sadiku | Janet O. Sadikuijtsrd
Energy becomes sustainable if it meets the needs of the present without compromising the ability of future generations to meet their own needs. Some of the definitions of sustainable energy include the considerations of environmental aspects such as greenhouse gas emissions, social, and economic aspects such as energy poverty. Generally far more sustainable than fossil fuel are renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy sources. Worthy of note is that some renewable energy projects, like the clearing of forests to produce biofuels, can cause severe environmental damage. The sustainability of nuclear power which is a low carbon source is highly debated because of concerns about radioactive waste, nuclear proliferation, and accidents. The switching from coal to natural gas has environmental benefits, including a lower climate impact, but could lead to delay in switching to more sustainable options. “Carbon capture and storage” can be built into power plants to remove the carbon dioxide CO2 emissions, but this technology is expensive and has rarely been implemented. Leading non renewable energy sources around the world is fossil fuels, coal, petroleum, and natural gas. Nuclear energy is usually considered another non renewable energy source, although nuclear energy itself is a renewable energy source, but the material used in nuclear power plants is not. The paper addresses the issue of sustainable energy, its attendant benefits to the future generation, and humanity in general. Paul A. Adekunte | Matthew N. O. Sadiku | Janet O.

Concepts for Sudan Survey Act Implementations Executive Regulations and Stand...ijtsrd
This paper aims to outline the executive regulations, survey standards, and specifications required for the implementation of the Sudan Survey Act, and for regulating and organizing all surveying work activities in Sudan. The act has been discussed for more than 5 years. The Land Survey Act was initiated by the Sudan Survey Authority and all official legislations were headed by the Sudan Ministry of Justice till it was issued in 2022. The paper presents conceptual guidelines to be used for the Survey Act implementation and to regulate the survey work practice, standardizing the field surveys, processing, quality control, procedures, and the processes related to survey work carried out by the stakeholders and relevant authorities in Sudan. The conceptual guidelines are meant to improve the quality and harmonization of geospatial data and to aid decision making processes as well as geospatial information systems. The established comprehensive executive regulations will govern and regulate the implementation of the Sudan Survey Geomatics Act in all surveying and mapping practices undertaken by the Sudan Survey Authority SSA and state local survey departments for public or private sector organizations. The targeted standards and specifications include the reference frame, projection, coordinate systems, and the guidelines and specifications that must be followed in the field of survey work, processes, and mapping products. In the last few decades, there has been a growing awareness of the importance of geomatics activities and measurements on the Earths surface in space and time, together with observing and mapping the changes. In such cases, data must be captured promptly, standardized, and obtained with more accuracy and specified in much detail. The paper will also highlight the current situation in Sudan, the degree to which survey standards are used, the problems encountered, and the errors that arise from not using the standards and survey specifications.

Towards the Implementation of the Sudan Interpolated Geoid Model Khartoum Sta...ijtsrd
The discussions between ellipsoid and geoid have invoked many researchers during the recent decades, especially during the GNSS technology era, which had witnessed a great deal of development but still geoid undulation requires more investigations. To figure out a solution for Sudans local geoid, this research has tried to intake the possibility of determining the geoid model by following two approaches, gravimetric and geometrical geoid model determination, by making use of GNSS leveling benchmarks at Khartoum state. The Benchmarks are well distributed in the study area, in which, the horizontal coordinates and the height above the ellipsoid have been observed by GNSS while orthometric heights were carried out using precise leveling. The Global Geopotential Model GGM represented in EGM2008 has been exploited to figure out the geoid undulation at the benchmarks in the study area. This is followed by a fitting process, that has been done to suit the geoid undulation data which has been computed using GNSS leveling data and geoid undulation inspired by the EGM2008. Two geoid surfaces were created after the fitting process to ensure that they are identical and both of them could be counted for getting the same geoid undulation with an acceptable accuracy. In this respect, statistical operation played an important role in ensuring the consistency and integrity of the model by applying cross validation techniques splitting the data into training and testing datasets for building the geoid model and testing its eligibility. The geometrical solution for geoid undulation computation has been utilized by applying straightforward equations that facilitate the calculation of the geoid undulation directly through applying statistical techniques for the GNSS leveling data of the study area to get the common equation parameters values that could be utilized to calculate geoid undulation of any position in the study area within the claimed accuracy. Both systems were checked and proved eligible to be used within the study area with acceptable accuracy which may contribute to solving the geoid undulation problem in the Khartoum area, and be further generalized to determine the geoid model over the entire country, and this could be considered in the future, for regional and continental geoid model.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Black Cotton Soil:
Rich proportion of montmorillonite is found in Black cotton
soil from mineralogical Analysis. A high percentage of
montmorillonite renders high degree of expansiveness.
These property results cracks in soil without any warning.
These cracks may sometimes Extent to the severe limit like
½” wide and 12” deep. So building to be founded on this soil
May suffer severe damage with the change of atmospheric
conditions. Black cotton soils Are inorganic clays of medium
to high compressibility and form a major soil group in India.
They are characterized by high shrinkage and swelling
properties. This Black Cotton soils occurs mostly in the
central and western parts and covers approximately 20% of
the total area of India. Because of its high swelling and
shrinkage characteristics, the Black cotton soils (BC soils)
have been a challenge to the highway engineers. The Black
Cotton soils are very hard when dry but lose its strength
completely when in wet condition. It is observed that on
drying, the black cotton soil develops cracks of varying
depth. As a result of the wetting and drying process, vertical
movement takes place in the soil mass. These movements
lead to failure of pavement, in the form of settlement heavy
depression, cracking and unevenness.

CONCLUSIONS
In this study, the major properties studied are OMC, MDD,
CBR, UCS, and Consolidation. Based on all investigations on
all samples and when compared with normal soil, the
following conclusions were made
Compaction Test and CBR Test:
In Standard Procter Test, the increase in lime
percentage the dry density increases up to 4% and after
the MDD value has been decreasing trend. Though, a
decrease in OMC has been observed with an increase in
lime %
Taking lime 4% as constant varying different % of fly
ash and observe the dry density and MDD values.
Maximum dry density was increased with the addition
of Fly ash
When 5%,10%,15%,20% FA added, higher MDD
observed for 15% FA
Unsoaked condition of CBR was studied and Peak value
was obtained at 20% conditions.
Soaked condition of CBR was studied and Peak value
was obtained at 15% in conditions.
Unconfined compressive strength:
In UCS, Due to an increase in FA percentage the UCS
value having increasing trend with respecttotheparent
soil.

@ IJTSRD | Unique Paper ID – IJTSRD26442 | Volume – 3 | Issue – 5 | July - August 2019 Page 667
In UCS, Due to an increase in percentage, the UCS value
has been observed increasing trend upto20% afterthat
having a decreasing trend with an increase in lime
content.
Lime not only acts as an activator in this case but also
reduces the plasticity of the soil.
FA soil specimen fails by theformationofvertical cracks.
The Curing period of the mix is a governing parameter
as the chemical reaction of stabilizersisdependsonit.so
it can be concluded that the strength will increase with
the increase in the curing period.
UCS of treated soils was higher than that of untreated
soils.
UCS value of the sample is increased from 0.97 to 8.8
kg/cm2
Addition of combination of FA with LIME makes the soil
mixes durable, low cost and effective for soil
stabilization.
DFS is greater than 35%, its expansiveness should be
considered
As per Holtz (1969) classified expansive soils based on
clay content, based on plasticity Index (%) Swelling
potential becomes “Medium”
As per Chen (1988) classified on expansive soils based
on plasticity index (%) Based on plasticity Index (%)
Swelling potential becomes “High”
