Partial Replacement of Cement in Concrete with Granite Powder and Fine Aggregate with Saw Dust Ash and Quarry Dust

Abstract

Abstract: The partial replacement of cement and fine aggregate with granite powder and saw dust ash, quarry dust when it is able for sustainable development is characterized by application, we came to know that a lot of damage is done to environment in the manufacturing of cement that the ton of cement manufacture releases half ton of co2 and control of the granite powder same way granite powder and saw dust is cheaper in cost. In this investigation of granite slurry and saw dust was used to partial substitute in proportions varying from 10%, 20%, 30% by weight to cement in concrete and tested from compressive strength, tensile strength and flexure strength. Concrete cubes measuring. 150 x 150 x 150 mm were cast and their compressive strength, tensile strength and flexure strength is evaluation at 7, 14, 21, 28 days. It was observed that replacement at 10% of cement by weight with granite powder in concrete was the most effective in increasing compressive and flexural strength compare to other ratios. The test results were plotted for 10% ratio of granite slurry and saw dust having great compressive strength, tensile strength and flexure strength compared to 20%, 30% ratio. So it can be concluded that when locally available granite slurry and saw dust is a good partial replacement to concrete and improves compressive, tensile, workability, flexure characteristics of concrete, while simultaneously offsetting the overall cost of concrete substantially.
