An Experimental Study on Partial Replacement of Sand by Blue Metal Dust and Iron Scrap in Standard Concrete

Vipul Sharma, Dr. Vishnu Sharma

Blue metal Dust, iron Scrap, strength, Durability etc.

In this study partial replacement of sand is done by Blue metal Dust and iron scrap in different percentage in concrete.In first category sand has been partially replaced by iron scrap having constant proportion of 5% and Blue metal Dust  having 10%, 15% ,20% 25%,30%,35%, 40% partial replacement.

In second category sand has been partially replaced by Iron scrap proportion of 10%,15%,20%,25%,30%, 35% and Blue Metal dust by 20%, 25%, 30% 35% and 40% replacement, several cubes have been cast for determining the compressive strength and workability split tensile strength.

For this purpose standard concrete of grade M 20 in a design mix proportion was formed and then tested for compressive , tensile and flexure strength and also checked against durability.
