The rapid growth of the population leads to a requirement of infrastructure this leads to scarcity of raw material for construction such as cement and sand. The other hand pollution growing due to thermal power plants, granite polishing unit and plastic waste this need to be removed. This gives an idea of using this compound as a raw material in concrete making. This concept found to effective minimizes disposal of fly, granite power and plastic wastes, and leads towards Green Building Concepts. In this investigation of M25 grade normal concrete is made by cement, sand, and aggregate which is tested and compared by special concrete. The concrete mix is prepared as per 10262 -2019 by adding replacing small amount of Fly ash in place of cement OPC 53 grade, and fine aggregate is prepared by partial replacing with granite powder (0%,10%,20%,30%)and another mix is prepared by adding 0.5 nylon fiber, partial replacement of fine aggregate with granite powder (0%,10%,20%,30%)specimens are casted . The casted specimens are tested for split tensile strength and compressive strength 7, 14 and 28 day’s respectively and these results also compared with each other. I t is observed that compressive strength and split tensile of concrete at 28days of curing show max value when compared with normal concrete. When the percentage of granite powder increases to 30% it shows that a decrease in both split tensile strength of concrete and compressive strength. When we added fiber to the concrete there is an increase in compressive strength and split tensile strength but there is a not much increase in compressive strength but increase in split tensile strength

Now a days increase in population increases the demand of concrete for construction purpose and Aggregates are the important constituents in concrete.Re-use of demoliation waste avoids the problem of waste disposal and is also helpful in reducing the gap between demand and supply of fresh aggregates. This research deals with partial replacement of natural coarse aggregates (NCA) with recycled coarse aggregates (RCA) of age group 30 years and 35 years in different proportions like 20%, 30%, 40% . For this, M20 grade of concrete is adopted. Curing of specimens were done for 7days and 28 days to attain the maximum strengths. Partial replacement of fine aggregate with Granite powder at 5%, 10%, 15% were done to reduce the waste percentage as well to gain more strength. After casting the specimens of RCA with Granite powder replacement, curing was done and the specimens were tested for compressive and tensile strengths. Obtained results of compressive and tensile strengths of RCA concrete mix were compared with conventional concrete. In this direction, an experimental investigation of compressive and tensile strength was undertaken to use RCA as a partial replacement in concrete. It was observed that the concrete with recycled aggregates of 30years and 35years age group achieved maximum compressive strength of 29.03 N/mm2 , 28.96 N/mm2 and tensile strength of 11.91 N/mm2 , 10.34 N/mm2 were obtained at 40%replacement of RCA respectively. It is found that the compressive strength and Split tensile strength of RAC with copper slag was increased 8.20% and 2.90% when compared with the RAC.

Due to rapid industrialization extensive quantity of waste materials like fly ash, silica fume, rice ash husk, and ferrochrome ash etc. are generated. Ferrochrome ash is generated from Ferro-alloy industry and fly-ash is produced in thermal power plants are alternative materials which have the potential of being utilized in concrete as a mineral admixture. The present investigation considers the combined influence on strength of concrete using various percentage fly ash and ferrochrome ash as partial replacement of cement. Experiments are carried out to get mechanical properties of ordinary Portland cement by replacement of fly ash by 10%, 20%, 30 % and 3% by ferrochrome ash. Mechanical properties are measured by determining compressive strength, split tensile strength and flexural strength. It can be inferred from the study that a small amount of ferrochrome ash mixed with 30 % fly-ash gives higher compressive strength as compared to fly ash alone. Addition of ferrochrome ash also increases the split tensile strength of concrete. Since ferrochrome ash and fly-ash are both industrial waste, utilization of these waste materials reduced the burden of dumping and greenhouse gas and thereby produce sustainable concrete.

Natural river sand is one of the important constituent materials in concrete production while stone dust is a material obtained from crusher plants which is also sometimes being used either partially or fully in replacement of natural river sand in concrete production. Use of stone dust in concrete not only improves the quality of concrete but also conserve the natural river sand. However, due its scarcity and environmental degradation caused resulting from excessive mining of Natural river sand, there is need to investigate an alternative material of the same quality which can replace river sand in concrete production. In the present study, experiments were carried out to study the gradation of aggregates, workability, compressive strength and split tensile strength of concrete made using quarry dust as replacement of fine aggregate at 0, 25, 50, 75, and 100%. Grade M15 of concrete was produced with ordinary Portland cement (OPC) for referral concrete while M25 of concrete was prepared for compressive strength and split tensile strength concrete. Workability and Compressive strength were determined at different replacement level of fine aggregate and optimum replacement level was determined based on compressive strength. Results showed that by replacing 50% of fine aggregate with quarry dust, concrete of maximum compressive strength can be produced as compared to all other replacement levels. The effect of quarry dust on compressive strength and split tensile strength was investigated and from the overall result obtained, it was observed that the compressive strength and split tensile strength increased significantly for all the curing ages from 0% to 50% replacement level of quarry dust. Maximum value obtained for 28day compressive and tensile strength were 25N/mm2 and 2.3N/mm2 respectively and this occurred at 50% replacement.

The World

The most widely used material in the world is concrete, consequently there is a large requirement for raw material of concrete such as Fine Aggregate, Coarse Aggregate and cement. the huge extraction of the aggregate for manufacturing of concrete as serious effect on the environment due to depletion of natural resources and pollution. This affects the eco system to great extent. Hence the project deals with finding replacement for the existing raw material used in concrete by replacing the fine aggregate from river which is largely used in construction by chiton shell. Sea shell is the corpus of the marine organism. The sea shell has been grinded to 4.75mm and then replaced in the concrete. M20 mix was used and cubic specimen were casted for 5 different percentage of partial replacement as 0%, 5%, 10 %, 20%, and 25 %. All the specimens are tested for 7 & 28 days compressive, flexural and split tensile strength. it has been noted that the highest strength is obtained for 25% replacement of chiton shell. it was also observed that  addition of sea shell power in concrete reduced workability hence superplasticizer were added to improve the consistency.
