In modern days concrete made with cement is probably the most widely used artificial material in the world. Despite this fact, concrete production is one of the concerns worldwide that impact the environment with a huge impact being global warming due to carbon dioxide emission during the production of portland cement. On the other hand, when industrial wastes are recycled or reused, Carbon dioxide(CO2) emissions are reduced and a small amount of material is dumped in a landfill and natural resources are saved. Therefore an attempt is made to replace the cement with granite powder in concrete. In this study, the possibility of using granite powder with cement on the performance of fresh and hardened concrete. In this experimental study, granite powder is used in concrete as cementitious material a partial replacement of cement. The replacement of cement was made by the level of 6%, 12%, and 20% by weight of cement. For each replacement, a compressive strength test was conducted. Compressive strength after 7days, 14days, and 28 days curing was done. From the test results, it was found that concrete at the level of 20% partial replacement of cement with granite powder had better workability and strength of 14 days and 28 days curing. The granite powder is available easily and is free of cost. So it seems to be economical.
