An Experimental Study on the Mechanical and Durability Properties of Concrete: Partial Replacement of Fine Aggregate with Steel Slag, Manufacturing Sand and Bottom Ash

Abstract

As construction industries are increasing at faster rate consumption of naturally available sand is more now-a-days. The fine aggregate which we use for construction is available from natural rivers and streams use of large amount of fine aggregate affects the environment. This present study had been carried out to investigate the possibility of utilizing a broad range of concrete raw materials as partial replacement for fine aggregate in the production of concrete. In this study replacement of fine aggregate with steel slag, M-sand and bottom ash with 10%, 20%, 30%, 40%and 50% for grade of concrete M30are tested for finding fresh and hardened properties of concrete to identify the optimum percentage of three fine aggregate replacement materials in concrete. M30 grade of concrete tested in compressive strength at the age of 28, 56, 90 and 180 days, flexural strength and modulus of elasticity at the age of 28 days curing and also to determine the durability properties of replacement materials concrete. Rapid Chloride Penetration Test, Salt resistance and Sulphate Resistance are to be conducted. Using origin pro software to arrive formulate regression equations for the properties of concrete.
