EXPERIMENTAL STUDY ON CONCRETE WITH REPLACEMENT OF COARSE AGGREGATE BY USING GRANITE WASTE

Civil Engineering/Structural Engineering

Aggregates are the important constituents in concrete. Nowadays some alternative materials have been already used as part of coarse aggregates in concrete. For example light weight aggregate, Recycled aggregate etc. In this paper is mainly focused on utilizing the Granite waste as a replacement of coarse aggregate in concrete work is investigated. Granite is an igneous rock which is widely used as construction material in different forms. Granite industries produce lot of waste materials. The wastes from the granite industries are being disposed to open land which is cause hazard to environment. This granite waste can be utilized for the preparation of concrete as replacement of coarse aggregate. In order to explore the possibility of utilizing the granite waste as replacement to coarse aggregate, an experimental investigation has been carried out. The percentages of granite waste added by 25%, 50%, 75% and100% Replace for coarse aggregate in concrete. Tests conducted for material using in concrete. Design mix of M30 is adopted for this paper and mix compositions were calculated by IS method. Cubes, Cylinders and Beams are to be casted. Compressive strength, split tensile strength and flexural strength are to be found at 7, 14 and 28 days. The test results indicate that the replacement of coarse aggregate by granite waste has beneficial effect on the mechanical properties such as compressive strength, split tensile strength and flexural strength of concrete.
