This document summarizes a study on the influence of mineral fillers on the properties of hot mix asphalt. The study investigated the effects of adding hydrated lime, fly ash, and phosphogypsum as fillers to bituminous concrete mix. Tests were conducted to determine the creep characteristics, stiffness modulus, and dynamic modulus of mixes containing different amounts of the mineral fillers. The test results showed that mixes with hydrated lime as a filler generally exhibited improved properties compared to mixes with other fillers or the base mix. In particular, hydrated lime led to higher creep stiffness and dynamic modulus values, indicating it improves the asphalt mix's ability to distribute loads and resist deformation under traffic.
This document studied the use of fine volcanic ash to modify asphalt mixtures. Testing showed that volcanic ash improved the high and low temperature properties of asphalt mastic and mixtures compared to mixtures modified with slag alone. Specifically, volcanic ash increased the rutting factor and creep stiffness of mastic at high and low temperatures. When combined with polymers like SBS, volcanic ash provided greater improvements to high temperature properties than slag. Additionally, volcanic ash modified mixtures had equal or better pavement performance as slag mixtures at a lower cost. Therefore, the study concluded volcanic ash is a suitable and cost-effective filler for modifying asphalt mixtures to enhance pavement performance.
The document discusses a study that evaluated the performance of asphalt concrete mixes containing granular volcanic ash as a partial replacement for conventional aggregate. Four mix designs were tested with 0%, 10%, 20%, and 30% volcanic ash content by total aggregate weight. Testing showed that mixes with up to 20% volcanic ash met Marshall design specifications. Mixes with volcanic ash required slightly more asphalt but had comparable stability to the control mix. Additional testing found that mixes with 10% volcanic ash performed optimally in terms of resistance to stripping, creep, fatigue life, and resilience. The study aims to utilize volcanic ash waste in road construction and reduce related environmental and disposal impacts.
IRJET-An Experimental Study on Effect of Partial Replacement of Normal Weight...IRJET Journal
This document presents the results of an experimental study on the effect of partially replacing normal weight aggregates with combinations of lightweight aggregates in fly ash-based geopolymer concrete. Lightweight aggregates used included pumice, LECA (lightweight expanded clay aggregate), and sintagg. Concrete mixtures with replacement levels from 0-20% for each combination were tested. Fresh and hardened properties like slump, compressive strength, split tensile strength, and flexural strength were evaluated after oven curing for various time periods. Test results showed that use of lightweight aggregates reduced concrete density and improved workability while maintaining adequate strength levels.

A Review Paper on Strength Development of SCMS Based Geopolymer Cementijtsrd
Ten to 50 of the world's total carbon dioxide emissions come from producing cement. The global warming gas is discharged once stone and clays are crushed and heated to high temperatures. New age concrete is outlined as a concrete that uses the waste product as a minimum of one among its parts, or its production method doesnt cause environmental destruction, or its high performance and life cycle property. Varied efforts are conducted by researchers to make some alternatives that can considerably cut back high energy consumed and environmental impacts throughout the fabrication method of cement, together with implementing the idea of commercial ecology. The cleaner technologies in concrete production, like work comparatively high proportion of cement by fly ash up to 100 , the utilization of different natural pozzolans, development of concrete with usage or waste materials, and developing of new age concrete by using polymerization of concrete the present reviews about performance of geopolymer concrete with the SCM materials Fly ash and GGBS M.

This study investigated the behavior of hot mix asphalt (HMA) containing steel slag aggregate (SHMA) compared to HMA containing granite aggregate (GHMA). SHMA showed higher strains than GHMA when exposed to temperature changes, except at void fractions over 4.5%. SHMA also demonstrated improvements in rut resistance, tensile strength, and toughness compared to GHMA. The dynamic modulus of SHMA was higher than GHMA at all temperatures tested. Properly treated SHMA can significantly improve HMA performance.

Experimental Study on Durability Characteristics of High Performance Concrete...theijes
High performance concrete (HPC) is developed gradually over the last 15 years with respect to production of concrete with higher and higher strength. To enhance the properties such as durability, strength, workability, economy has increased due to the usage of mineral admixtures in making high performance concrete. The scope of the present study is to investigate the effect of mineral admixtures and by-products towards the performance of HPC. An effort has been made to concentrate on the mineral admixture of silica fume towards their pozzolanic reaction and industrial by-product of bottom ash and steel slag towards their hydration reaction can be contributed towards their strength and durability properties. The strength characteristics such as compressive strength, tensile strength and flexural strength were investigated to find the optimum replacement of mineral admixture and by-product admixture. HPC with mineral admixture of silica fume at the replacement levels of 0%, 5%, 10%, 15% & 20% were studied at the age of 28 days and industrial by-products of bottom ash and steel slag aggregate at the replacement level of 10%, 20%, 30%, 40% & 50% were studied at the age of 28 days. There were a total of 15 mixes created with different material contents. Out of 14 were HPC mixes and 1 were conventional concrete mixes. Finally strength has enhanced with the mix of silica fume can replaced by cement with 5% and bottom ash and steel slag can replaced by fine and coarse aggregate with 10% can be achieved higher strength when compared with other percentage of mixes. The combination mixes can be classified as binary and ternary mixes. Binary mixes involved combinations of silica fume and bottom ash (SF+BA), silica fume and steel slag aggregate (SF+SSA), bottom ash and steel slag aggregate (BA+SSA) and Ternary mixes involved combination of three materials such as silica fume, bottom ash and steel slag aggregate (SF+BA+SSA) in High performance concrete. The investigation revealed that the combined use of silica fume, bottom ash and steel slag aggregate improved the mechanical properties of HPC and thus there 3 materials may use as a partial replacement material in making HPC. The durability studies such as acid resistance, salt resistance, sulphate resistance & water absorption were conducted. From the experimental investigation, it was observed that mineral admixture of silica fume and industrial by-products of bottom ash & steel slag aggregate plays a vital role in improving the strength and durability parameter itself.
EXPERIMENTAL INVESTIGATION ON PROPERTIES OF HIGH STRENGTH CONCRETE USING POZZ...IAEME Publication
In this paper, high strength concretes (HSC) containing manufactured sand (or
maybe called crushed sand) as fine aggregate in the presence of fly ash (FA), silica
fume (SF) were made. The HSC mixtures were designed to achieve 28-day
compressive strength beyond 55 MPa. Compressive strength, drying shrinkage, watertightness
and sulfate attack tests were conducted to evaluate the feasibility on the
production of HSC having crushed sand, FA and SF. The test results indicated that the
compressive strength of all HSC mixtures exceeded 55 MPa at 28 days. There was an
improvement in the compressive strength following the addition of SF in HSC.
Introducing crushed sand to HSC as fine aggregate led to a reduction in compressive
strength. The usage of crushed sand most effectively decreased the length change of
HSC, compared with HSC containing natural sand. HSC mixtures can be classified
into > B12 water-tightness class. Furthermore, weight loss of HSC was in a range of
0.040.29%.

This document summarizes an experimental investigation into using local Sudanese aggregates to produce high-strength concrete with a compressive strength of 80 MPa. Hundreds of specimens were made using marble and granite aggregates from Sudan along with supplementary cementitious materials like silica fume and fly ash. The concrete achieved the target strength and the aggregates were found to be suitable for high-strength concrete. A second part of the study evaluated the drying shrinkage of the high-strength concrete and found only a weak relationship between higher strength and increased shrinkage. The research aims to support a project heightening an existing dam in Sudan using locally available materials.
Effect of Superplasticizer and Silica Fume on Properties of ConcreteIDES Editor
Nowadays high strength and high performance
concrete are widely used in many civil engineering
constructions. To produce them it is required to reduce the
water/powder ratio and increase the binder content.
Superplasticizers are commonly used to achieve the
workability. Silica fume is one of the popular pozzolanas used
in concrete to get imporved properties. The use of silica fume
in conjuction with superplastisizers has become the backbone
of high strength and high performance concrete. An
experimental program has been carried out to study the effect
of superplasticizer alone and in conjuction with silica fume
on some of the properties of fresh and harden of concrete.

Hundreds of specimens were made using marble and granite aggregates from Sudan along with supplementary cementitious materials like silica fume and fly ash. The concrete achieved the target strength and the aggregates were found to be suitable for high-strength concrete. A second part of the study evaluated the drying shrinkage of the high-strength concrete and found only a weak relationship between higher strength and increased shrinkage. The research aims to support a project heightening an existing dam in Sudan using locally available materials.
Effect of Superplasticizer and Silica Fume on Properties of ConcreteIDES Editor
Nowadays high strength and high performance
concrete are widely used in many civil engineering
constructions. To produce them it is required to reduce the
water/powder ratio and increase the binder content.
Superplasticizers are commonly used to achieve the
workability. Silica fume is one of the popular pozzolanas used
in concrete to get imporved properties. The use of silica fume
in conjuction with superplastisizers has become the backbone
of high strength and high performance concrete. An
experimental program has been carried out to study the effect
of superplasticizer alone and in conjuction with silica fume
on some of the properties of fresh and harden of concrete.

Experimental Investigations of Mechanical properties on Micro silica (Silica ...IOSR Journals
Abstract : The Now a day, we need to look at a way to reduce the cost of building materials, particularly
cement is currently so high that only rich people and governments can afford meaningful construction. Studies
have been carried out to investigate the possibility of utilizing a broad range of materials as partial replacement
materials for cement in the production of concrete. This study investigated the strength properties of Silica fume
and fly ash concrete. This work primarily deals with the strength characteristics such as compressive, Split
tensile and flexural strength. High performance concrete a set of 7 different concrete mixture were cast and
tested with different cement replacement levels (0%, 2.5%, 5%, 7.5%, 10% 12.5% and15%) of Fly ash (FA) with
silica fume (SF) as addition ( 0%,5%,10 % ,15% ,25and 30%) by wt of Cement and/or each trial super
plasticizer has been added at constant values to achieve a constant range of slump for desired work ability with
a constant water-binder (w/b) ratio of 0.30.Specimens were produced and cured in a curing tank for 3, 7, 14
and 28 days. The cubes were subjected to compressive strength tests after density determination at 3,7,14 and
28 days respectively. The chemical composition and physical composition of micro silica, FlyAsh and cement
were determined. The density of the concrete decreased with increased in percentage of micro silica and Fly ash
replacement up to 15%. Increase in the level of micro silica fume and Fly ash replacement between 30% to 45%
led to a reduction in the compressive strength of hardened concrete. This study has shown that between 15 to
22.5% replacement levels, concrete will develop strength sufficient for construction purposes. Its use will lead
to a reduction in cement quantity required for construction purposes and hence sustainability in the
construction industry as well as aid economic construction.

This study examined the effects of different proportions of light weight expanded clay aggregates on the compressive and flexural strength of concrete. Concrete mixtures were prepared with 0%, 25%, 50%, 75%, and 100% replacement of coarse aggregates with expanded clay aggregates. The mixtures also included 10% silica fume and 1.6% polyvinyl alcohol to replace cement and water. Test results found that compressive and flexural strength decreased as the expanded clay aggregate content increased. However, the densities of the concretes were significantly lower than conventional concrete, indicating light weight concrete is suitable when self-weight needs to be reduced.
This study investigated the effects of using different percentages of expanded clay aggregates (ECA) as a replacement for normal coarse aggregates in concrete. Concrete mixtures were prepared with 0%, 25%, 50%, 75%, and 100% replacement of ECA and tested for compressive strength and flexural strength after 28 days of curing. The results showed that as the percentage of ECA increased, the density and strengths of the concrete decreased. Concretes with higher ECA content achieved lower compressive strengths but still met the requirements for structural lightweight concrete. The study concluded that this lightweight concrete can be used in places where external forces are minimal as its strength is only sufficient to support its own weight.

This document discusses a study on the chemical and physical properties of composite cements containing micro-silica (SF) and nano-silica (NS). Portland cement was partially substituted with SF up to 15% by mass, then the SF portion was replaced with equal amounts of NS ranging from 2-6% by mass. The hydration behavior, mechanical properties, and microstructure of the cement blends were analyzed. The results showed that both SF and NS improved the hydration and strength compared to plain cement, but NS provided greater improvements due to its higher surface area and pozzolanic activity. The optimum blend was found to be 85% cement, 11% SF, and 4% NS.
This study examined the compressive strength of concrete containing steel fibers and mineral admixtures. Concrete cubes were made with cement replaced by 2-10% silica fume and 10% fly ash, and steel fibers added at 0.5-2% by weight. The cubes were tested for compressive strength at 3, 7, and 28 days. The results showed that compressive strength generally increased with the addition of up to 1.5% steel fibers. The optimum mix was found to be 10% fly ash, 8% silica fume, and 1.5% steel fibers, which achieved strengths comparable to plain concrete without changing workability much.
This document summarizes an experimental study on using steel fibers and mineral admixtures like silica fume and fly ash to improve the properties of hardened concrete.

Analysis of Admixtures and Their Effects of Silica Fumes, Metakaolin and PFA...IJMER
This paper presents a review of the properties of fresh concrete including workability, heat
of hydration, setting time, bleeding, and reactivity by using mineral admixtures fly ash (FA), silica
fume (SF), ground granulated blast furnace slag (GGBS), metakaolin (MK), and rice husk ash (RHA).
Comparison of normal and high strength concrete in which cement has been partially supplemented
by mineral admixture has been considered. It has been concluded that mineral admixtures may be
categorized into two groups: chemically active mineral admixtures and microfiller mineral
admixtures. Chemically active mineral admixtures decrease workability and setting time of concrete
but increase the heat of hydration and reactivity. On the other hand, micro filler mineral admixtures
increase workability and setting time of concrete but decrease the heat of hydration and reactivity. In
general, small particle size and higher specific surface area of mineral admixture are favourable to
produce highly dense and impermeable concrete; however, they cause low workability and demand
more water which may be offset by adding effective super plasticizer.

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks.

ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.

A MULTIPLE – CHANNEL QUEUING MODELS ON FUZZY ENVIRONMENTIAEME Publication
In this paper, we investigated a queuing model of fuzzy environment-based a multiple channel queuing model (M/M/C) ( /FCFS) and study its performance under realistic conditions. It applies a nonagonal fuzzy number to analyse the relevant performance of a multiple channel queuing model (M/M/C) ( /FCFS). Based on the sub interval average ranking method for nonagonal fuzzy number, we convert fuzzy number to crisp one. Numerical results reveal that the efficiency of this method. Intuitively, the fuzzy environment adapts well to a multiple channel queuing models (M/M/C) ( /FCFS) are very well.
