Abstract: 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.
