Experimental investigation on high strength concrete by using GGBS and polycarboxylate ether

Abstract

Concrete is a mixture of cement, fine aggregate, coarse aggregate and water. Concrete plays a vital role in the development of infrastructure Viz., buildings, industrial structures, bridges and highways etc. leading to utilization of large quantity of concrete. On the other side, cost of concrete is attributed to the cost of its ingredients which is scarce and expensive, this leading to usage of economically alternative materials in its production. This requirement is drawn the attention of investigators to explore new replacements of ingredients of concrete. The present technical report focuses on investigating characteristics of concrete with partial replacement of cement with Ground Granulated Blast furnace Slag (GGBS) and fully replacement of R-sand with M-sand. The topic deals with the usage of GGBS and advantages as well as disadvantages in using it in concrete. Here polycarboxylate ether is used to reduce the water content. Tests are carried at 7days, 14days, 28days.
