Abstract Aggregates are the major contribution to develop any concrete mixture. In general, aggregates are used as a filler material in concrete and cement as binder. Studies and experiments were conducted to identify suitable materials which can replace coarse aggregate and fine aggregate and also shows a better performance than conventional materials. In this regards, the present study deals with the utilization of granite powder as a partial replacement for fine aggregate. Granite powder is added in 25, 50, 75, 100% replacement with fine aggregate and specimens were casted. The study also focuses to develop a concrete mix targeting high strength concrete mix combination. Evaluation of flexural properties was made by casting prism specimen with difference in percentage replacement of fine aggregate, water/cement ratio and age of curing. To enhance the workability property super plasticizer is also used. The test results shows irrespective of the variation in water/cement ratio it is observed that mix with 25% replacement exhibit a better performance than other mixes. From the study, it is concluded that maximum 25% replacement can be made with granite powder as fine aggregate. Top Keywords Aggregate, high strength, plasticizer, curing, flexural. Top |
