Abstract
AbstractIn construction industries, the usage of cement and fine aggregate gets increased rapidly. Due to the increasing demand and higher cost of cement and fine aggregate, cement is partially replaced by eggshell powder and fine aggregate by granite powder. Eggshell waste is evolved from poultry farms, restaurants and hotels and is made up of calcium which is very similar to cement. Calcium in concrete causes a substantial increase in strength and acts as an accelerator. Granite powder is obtained from granite industries while cutting huge rocks to the desired shape. The disposal of granite powder on land causes environmental hazards like air pollution. In this project, the effect of varying percentages of eggshell powder by the weight of cement and granite powder by the weight of fine aggregate is investigated without changing the mix M40. By utilizing the waste materials, specimens are cast and various tests are conducted such as compressive strength, split tensile strength, flexural strength. The behaviors of the concrete specimen are observed and compared with conventional concrete after 7 and 28 days testing.KeywordsEggshell powderGranite powderFine aggregate
