Strength behaviour of foundry sand on modified high strength concreteeSAT Journals
Abstract Metal foundries use a large amount of sand as part of the metal casting process. Foundry industries generally recycle and reuse the used foundry sand many times in casting process. When the sand can no longer be reused in the foundry, it is removed from the foundry and is termed as "foundry waste sand." Like many waste products, foundry sand has beneficial applications to other industries. A mixture of silica sand coated with a thin film of burnt carbon and residual binder with traces of dust is termed as foundry sand. From the previous available literature it was found that replacement of sand by foundry sand by certain initial percentages gives a marginal increase in hardened properties of normal strength concrete. In the present work, fine aggregate is replaced by foundry sand with percentages and tests were performed for hardened properties of modified high strength concrete for all replacement levels.

Excess demand of natural resources on account of expeditious urbanization and the scrapping problem of agricultural waste have paved the way for research in usage of organic waste in the construction industry. Scores of organic waste materials have found their usage in concrete as substitute alternatives for cement, fine aggregate, coarse aggregate and reinforcing materials. This paper highlights and examines some of the organic waste material used as partial replacement of fine aggregate in concrete which is being defined and termed as organic waste concrete in present context. The paper aims at evaluating the strength characteristics of organic waste concrete by using different organic wastes and thus understanding the feasibility of using each organic waste. Distinct properties of fresh and hardened concrete, their reliability when admixed with organic wastes are examined. It has been observed that the organic waste concrete containing groundnut shell, rice husk ash, saw dust ash demonstrated more desirable workability than their other substitutes did. Organic waste concrete containing bagasse ash, sawdust ash attained their required strength by 20% of replacement as fine aggregate which were maximum among all organic waste type concrete. Accurate comparison was predicted among compressive strength, flexural strength and tensile strength of organic waste concrete. Introduction of bagasse ash as fine aggregate in concrete improved the resilience to chloride tapping. After the careful investigation, it is of substantial conclusion that additional exploration and testing is justified on all fine aggregates substituting organic waste, which would give further certainty on their exploitation in concrete.

Natural river sand is expensive due to excessive cost of transportation from natural sources. Also large-scale depletion of these sources creates environmental problems, transportation and other constraints make the availability and use of river sand less attractive, a substitute or replacement product for concrete industry needs to be found. In such a situation the Stone dust can be an economic alternative to the river sand. Stone Dust can be defined as residue, tailing or other non-voluble waste material after the extraction and processing of rocks. Use of Stone dust as a fine aggregate in concrete draws serious attention of researchers and investigators. The use of Silica fume in concrete is desirable because of benefits such as useful disposal of a by-product, increased workability, reduction of cement consumption, increased sulfate resistance, increased resistance to alkali-silica reaction and decreased permeability. However, the use of fly ash leads to a reduction in early strength of concrete. However, the use of stone dust leads to a reduction in the workability of concrete. Therefore, the concurrent use of stone dust and silica fume in concrete will lead to the benefits of using such materials being added and some of the undesirable effects being negated. The decrease in early strength by the addition of silica fume is ameliorated by the addition of stone dust. The decrease in workability by the addition of stone dust is reduced by the addition of fly ash. This dissertation work presents the feasibility of the usage of Stone Dust as hundred percent substitutes for Natural river Sand and silica fume as ten percent substitutes for cement in concrete.

Effect of silica fume on the strength of cement mortareSAT Journals
Abstract
The replacement of sand/cement by certain percentage of silica fumes, resulted in the improvement in compressive strength of the mortar. Silica fumes to the highly pozzolanic materials because it consists essentially of silica in non- crystalline form with a high specific surface. It is used to improve the mechanical properties of the concrete. The main objective of this paper is to study the effect of silica fume on the compressive strength of mortar. Three proportions of mixes viz mix 1:3, mix 1:4 and mix 1:6 with different percentages of silica fumes replacement with sand/cement were used. The maximum increase in strength at the age of 28 days when sand is replaced by 15% of silica fume has been observed as 40% and in case of cement replaced with 15% of silica fume, the observed increase in compressive strength of mortar comes out to be 28%.
A quantitative cost analysis shows that with the replacement of cement and sand by silica fume, the in cost is more when sand is replaced and it is less when cement is replaced.

Experimental Study of Partial Replacement of Fine Aggregate with Waste Materi...IJRES Journal
The utilization of industrial and agricultural waste produced by industrial process has been the focus of waste reduction research for economical, environmental and technical reasons. This is because over 300 million tones of industrial waste are being produced per annual by agricultural and industrial process in India. The problem arising from continuous technological and industrial development is the disposal of waste material. If some of the waste materials are found suitable in concrete making not only cost of construction can be cut down, but also safe disposal of waste material can be achieved. The cement of high strength concrete is generally high which often leads to higher shrinkage and greater evaluation of neat of hydration besides increase in cost. A partial substitution of cement by an industrial waste is not only economical but also improves the properties of fresh and hardened concrete and enhance the durability characteristics besides the safe disposal of waste material thereby protecting the environment form pollution This paper deals with partial replacement of fine aggregate with the industrial waste from China Clay industries. The compressive strength, split tensile strength and flexural strength of conventional concrete and fine aggregate replaced concrete are compared and the results are tabulated.
Studies on quarry dust as partial replacement of fine aggregates in concreteIJLT EMAS
Natural sand is most commonly used fine aggregates
in the production of concrete possess the problem of acute
shortage in many areas. Quarry dust can be used as an economic
alternative to the natural sand. In this investigation an attempt is
made to utilize quarry dust as a partial substitute for natural
sand in producing concrete. Natural sand is replaced by Quarry
dust at an interval of 5%, 10%, 15%, 20% and 25%. Mix
proportions for M20 concrete is prepared with reference to IS:
10262-2009 and IS: 456-2000 for the study of workability.
Compressive strength and Flexural strength test results are
compared with the conventional concrete. The strengths were
obtained at the ages of 3, 7 and 28 days. Compressive and
Flexural strength increased marginally from 5% to 15%
replacement. There is a slight decrease in the corresponding
compressive and flexural strength at 20% replacement. Good
correlation was observed between compressive strength and
flexural strength. It was observed that the addition of quarry
dust that would replace the fine material at particular
proportion has displayed an enhancing effect on properties of
concrete. This investigation proves that quarry dust can be used
as a partial substitute for natural sand in preparing concrete.

The results of the present investigation indicate that marble dusts incorporation results insignificant improvements in the compressive, flexural and split tensile strengths of concrete and The load carrying capacity of RMP RCC beams {mix2 and mix3} is more compared to RCC conventional beams up to 10% of replacement and also for stone dusts and marble dust incorporation results insignificant improvements in the compressive strengths of concrete up to 20% of SD and 10% of MP of replacement.
Maintaining Data Confidentiality in Association Rule Mining in Distributed En...IJSRD
The data in real world applications is distributed at multiple locations, and the owner of the databases may be different people. Thus to perform mining task, the data needs to be kept at central location which causes threat to the privacy of corporate data. Hence the key challenge is to applying mining on distributed source data with preserving privacy of corporate data. The system addresses the problem of incrementally mining frequent itemsets in dynamic environment. The assumption made here is that, after initial mining the source undergoes into small changes in each time. The privacy of data should not be threatened by an adversary i.e. the miner and target database owner should not be able to recover original data from transformed data.
Performance and Emission characteristics of a Single Cylinder Four Stroke Die...IJSRD
The current trends in CI engine are to use Water-diesel emulsion as alternative fuel. It can be employed directly to the existing CI Engine system with no additional modifications. This system helps in reduction of NOx as well as PM, which in turn improve the combustion efficiency of the engine. However there are still investigations have to be done. The current work mainly concentrated on diesel engine run on water-diesel emulsions and its effect on engine performance and emissions were studied. The various loads were applied on a constant speed diesel engine run on water-diesel emulsions of varying ratios of 0.2:1, 0.3:1. 0.4:1 and 0.5:1. Emission and performance characteristics were measured and were compared with base diesel operation. The emissions like NOx and smoke density were found to decrease greatly and brake thermal efficiency was found to increase at high loads. Smoke level was 4.2 BSU and 3 BSU for base diesel and water diesel emulsion of 0.4. The ignition delay was found to increase with water diesel emulsions. This also increased the maximum rate of pressure rise and peak pressure. The engine was found to run rough with water-diesel emulsions. The optimal water-diesel ratio was found to be 0.4:1 by weight. HC and CO emissions were found to increase with water diesel emulsions.

Keystroke Dynamics Authentication with Project Management SystemIJSRD
Generally user authentication is done using username and password that is called as login process. This login process is not more secure because, however a login session is still unprotected to impersonator when the user leaves his computer without logging off. Keystroke dynamics methods can be made useful to verify a user by extracting some typing features then, after the authentication process has successfully ended. From the last decade several studies proposed the use of keystroke dynamics as a behavioral biometric tool to verify users. We propose a new method, for representing the keystroke patterns by joining similar pairs of consecutive keystrokes. The above proposed method is used to consider clustering the di-graphs which are based on their temporal features. In this project, authentication system is provide to project management system that make more Secure management system without acknowledging unauthorized user. The Project Management System addresses the management of software projects. It provides the framework for organizing and managing resources in such a way that these resources deliver all the work required to complete a software project within defined scope, time and cost constraints. The system applies only to the management of software projects and is a tool that facilitates decision making.

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.
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.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

I. INTRODUCTION
Aggregates have a significant influence on both rheological
and mechanical properties of mortars and concrete [Neville].
Their specific gravity, particle size distribution, shape and
surface texture influence markedly the properties of mortars
and concrete in the fresh state. On the other hand, the
mineralogical composition, toughness, elastic modulus and
degree of
In India, natural river sand (fine aggregate) is
traditionally used in mortars and concrete. However,
growing environmental restrictions to the exploitation of
sand from riverbeds have resulted in a search for alternative
sand, particularly near the larger metropolitan areas. This
has brought in severe strains on the availability of sand
forcing the construction industry to look for an alternative
construction material. Thus manufactured fine aggregates
appear as an attractive alternative to natural fine aggregates
for cement mortars and concrete.
Manufactured sand is totally different from natural
river sand. The surface characteristics are different. Most of
the artificial sand is irregular and more porous. Grading will
vary over wide range resulting in internal porosityand
reduction in workability of mortar or concrete. A number of
studies have dealt with the influence of both grading and
particle shape of the fine aggregate in mortars and concrete.
For good quality manufactured sand at a given water/cement
ratio, it has been found that concrete made with
manufactured sand achieved compressive strength equal to
or higher than concrete made with natural sand, reducing the
void content of the aggregate, thereby lubricating the
aggregate system without increasing the water requirement
of the mixture (Ind Manoj and Pal, 1998 and
Suhas, 2012).

III. EXPERIMENTAL INVESTIGATION
The experimental program of this project is designed to
investigate the use of Granulated blast Furnace Slag (GBFS)
and Quarry Dust (QD) as partially replacement of fine
aggregate in cement mortar. Before testing the specimen the
cube where casted in wooden mould and the size of the
cube is 70.7x70.7x70.7 mm [cast as per IS:4031 (2000)]
mortar mix 1:3 was selected for 20,40,60,80 and 100%
replacement of natural sand with Granulated Furnace Slag
(GBFS) and Quarry Dust (QD) for constant W/C of 0.55 and
all the cubes were casted and kept for curing at a period of
3,7 and 28 days after completion of curing period the cube
were removed from the water and all the cubes where tested
under a compressive testing machine. To investigate the
mortar flow behavior and its compressive strength.
A. Casting And Curing Of Specimen:
1) Casting Of Cement Mortar Cube:
Moulds of size 70.7mmx70.7mmx70.7mm Cast as per
IS:4031 (2000) are used for casting the cement mortar cube.
The moulds were cleaned and one coat of cutting oil was
applied on all the internal surfaces.
All the cube moulds were filled in 3 layers, the height
of each layer was 1/3rd height of the mould and for each
layer 25 blows were given with the help of tamping rod over
the entire cross section of the mould uniformly. After filling
and compacting the mould, the top surface was made
smooth.
A total No of 99 cubes are casted. The proportion
of materials which is used in the present study was 1:3 mix
proportion of mortars prepared by replacement of natural
sand by GBFS and QD particles and are designated as
GBFS0, GBFS20, GBFS40, GBFS60 GBFS80, GBFS100
and QD0, QD20, QD40, QD60, QD80, QD100 for the
cement mortar mix 1:3 with 0.55 w/c ratio. In all the
designations 0, 25, 50, 75 and 100 indicates the % of GBFS
and QD in cement mortar. Three cubes on each parameter
respectively by GBFS and QD replacement. A casting of
specimen is shown in fig 3.1 After 24 hours the sample were
demoulded as shown in fig 3.2.
Fig. 3.1: Casting of Specimen
Fig. 3.2: Casting of Specimen
2) Curing Of Specimen:
The curing of specimens is done by pounding method of
curing. Specimens are removed from the moulds and are
placed in tank containing water for required No of days of
curing. After the curing period specimens are taken out from
the tank and the surface moisture is removed by wiping the
surface with the cloth. Curing periods of 3 days, 7 days and
28 days were used in the investigation.
B. Testing Of Specimen:
1) Flowability Of Cement Mortar:
Workability of fresh cement mortar was measured by using
standard flow table apparatus as per IS: 5512 as shown in
Figure 3.5, 3.6, 3.7 & 3.8. The flow of cement mortar
decreased substantially for GBFS and QD mortar for all
replacement levels. As the finer material increases, more is
the surface area and hence more water is required for
wetting the surface. For the given fixed quantity of water as
the finer material increases the workability decreases. The
workability can be increased by adding suitable dosage of
chemical admixture.

Table 4.1. From the result it was observed that the
compressive strength of the cement mortar increases with
increase in the replacement level of sand by GBFS and QD
up to 60% .
GBFS For 3 days curing period, the strength of the
cement mortar is increased about 1.970%, and 16.73% and
19.32% and 5.27% for 20%, 40%, 60% and 80% and
decreased about 14.31% for 100% replacement level
respectively when compared with that of conventional
cement mortar.
And QD For 3 days curing period, the strength of
the cement mortar is increased about 2.73%, and 6.58% and
15.69% for 20%, 40%, and 60% and decreased about
13.163% and 29.68% for 80% and 100% replacement level
respectively when compared with that of conventional
cement mortar.
GBFS For 28 days curing period, the strength of
the cement mortar increased about 1.29% and 5.79% and
10.58% and 0.96% for 20%, 40%, 60% and 80% and
decreases about 4% for 100% replacement level respectively
when compared with that of conventional cement mortar. At

V. CONCLUSIONS AND FURTHER SCOPE
A. Conclusions:
The experimental results obtained show that partial
replacement of ordinary sand by granulated blast furnace
slag and quarry dust gives better results over the verified
range from 0, 20, 40, 60, 80 & 100 % replacement. The
conclusions are drawn as below.
Compressive strength values showed increase up to
60% sand replacement level by GBFS and QD
respectively. At 60% sand replacement level
mechanical properties were identical to that of
conventional cement mortar. Beyond 60% all the
strength values showed decrease when compared with
that of conventional cement mortar.
The maximum percentage increase in compressive
strength of GBFS at 60% sand replacement was
10.58%. for 28 days.
The maximum percentage increase in compressive
strength of QD at 60% sand replacement was 3.145%.
for 28 days.
The compressive strength compression between GBFS
and QD values showed increase up 60% sand
replacement by GBFS is 7.43% that of quarrydust.
• It can be concluded that concrete mix with sand
replacement by GBFS and QD will be an economical
and environmentally sustainable option.
For structural purpose we can use 100% replacement of
GGBS Sand.
B. Further Scope:
Long term strength studies up to 60 days and 90 days
for GGBS and QD cement mortar can be carried out.
Durability studies can be carried out for GGBS and QD
cement mortar.
Strength can be increased by using different super
plasticizers in GGBS and QD cement mortar.
