Abstract
Granite industry produce huge amount of waste material during cutting, mining and polishing stage. These wastes are dumped on the open field/land which creates lot of environmental problem as well as health problems. Therefore it is necessary to utilize this waste material as a construction material in concrete industry. In this research work, the experimental investigation carried out is to examine the feasibility of use of granite waste as a coarse aggregate in concrete. Five types of mixes are prepared with constant quantities of fine aggregate, cement and water, but natural coarse aggregate are replaced with granite waste at different percentages 0%, 20%, 40%, 60%, 80% by weight of concrete. The water-cement ratio of 0.57 was kept constant for all mixes. From the test results it was observed that the workability, compressive and flexure strength were increased. Compressive strength of concrete Mixes increased up to 20%, 40%, and 60% of granite compressive strength increase as +0.16%, 13.29%, and 29.14% at 28 days compressive strength respectively. Compressive strength decreased beyond 60% granite as coarse aggregate. For 80% granite strength decrease -7.46%. Flexural strength increased at 20% granite as +3.32%, flexural strength reduces beyond 20% granite, flexural strength at 40%, 60% and 80% of granite is -4.83%, -25.91% and -28.77% respectively.
