Experimental Investigation of Strength and Durability Properties of Concrete by using Industrial by Product Granite Powder and Polypropylene Fibre
This study focusing on experimental investigation of locally available granite industrial waste powder that is granite powder as fine aggregate and partial replacement of cement at constant rate. By this producing M30 concrete observe mechanical strength and durability properties of concrete. Influence water cement ratio and curing properties of concrete on mechanical properties of various mix proportions can be premeditated. The percentage of granite powder is added 0%, 12%, 14%, 16% replacement of fine aggregate. Cement can be replaced for cement at constant percentage at 7.5% weight of cement. For maintain workability super plasticizer is added at 1% by weight of cement. For improving the tensile strength of concrete adding polypropylene fibers to concrete at 0.2%, 0.4% and 0.6% by weight of cement. Durability test conducted on 60days and 90days concrete with 1N by using NAOH pellets, at constant pH of solution. Tests conducted on concrete are compressive strength, split tensile strength and alkalinity attack test. Our study is expected to give good results and future scope. This work gives us how effectively we can use the industrial by products and how to use recycled aggregates in modern concretes.
