Experimental Study of the Physical Properties of Concrete Prepared by Partial Replacement of Cement with Alccofine, Metakaolite and GGBS

Abstract

Abstract: Cement concrete is the most broadly used construction material in the world. Maintenance and repair work of concrete structures is an increasing problem involving the significant expenditure. As a result of study carried out worldwide, it has been made possible to process the material to satisfy more strong performance requirements, especially durability. To reduce the expenditure for making of concrete we should consider the industrial waste materials for partial replacement of cement with supplementary cementitious materials like alccofine, GGBS and meta-kaoline. We consider these materials because these are available at very low cost. For this purpose we prepared number of samples by the various mixes with variable percentage of these materials in the mix. After the selection of the mix on these prepared specimens we perform workability and compressive strength test in the laboratory. By these tests we come to know that when we replace cement by Alcofine up to 10% the compressive strength increases 414.53 but after this range of addition it starts reducing the strength. when we replace cement by GGBS up to 15% the compressive strength increases 421.40 but after this range of addition it starts reducing the strength and same when we replace cement by Meta-kaoline up to 10% the compressive strength increases 448.44 but after this range of addition it starts reducing the strength
