Experimental Study on Partial Replacement of Msand with Ground Granulated Blast Slag

Abstract

Solid waste management is the major threat in these days. There are various sources in which the wastes are generated, among those the major role is played by the industries. The industries manufacture a product by giving so many by-products. These by-products are simply dumped in the land which causes pollution. So, it should be treated as well as reused in one form or another. One such by-product is the Ground granulated blast slag which is obtained from the blast furnaces used to make iron. The demand for the construction materials leads to the replacement of new materials in the concrete. Proposed idea is to use the ground granulated furnace slag in the concrete. An experimental investigation is conducted to study the properties of concrete containing the ground granulated blast slag as the replacement of the fine aggregate. The fine aggregate is the manufactured sand. The manufactured sand is widely used nowadays due to the demand and the cost of the river sand. The GGBS is replaced for the manufactured sand by 30%,35%,40% and 45%. Then the strength is obtained by carrying out compression, split tensile and the flexural tests. Then the optimization value of the GGBS is found as 30% and the effect of size of coarse aggregate is found out with the optimized value of GGBS. Then the durability tests are carried out for the acid action due to sulphate, chloride, etc., Finally, the results are discussed and the conclusions are obtained.
