EXPERIMENTAL INVESTIGATION OF CONCRETE USING PARTIAL REPLACEMENT OF CEMENT WITH GGBS AND COARSE AGGREGATE WITH DEMOLISHING WASTE

Abstract

Traditionally, Ordinary Portland Cement concrete is used for making the civil structures. Rising construction costs and the need to reduce environmental stresses to make construction sustainable, has necessitated research into the use of alternative materials, especially locally available ones which can replace conventional materials used in concrete production. In the present study the experimental investigation were carried out to evaluate the effects of replacing cement with Ground Granulated Blast Furnace Slag (GGBS) and coarse aggregate with Demolishing Waste (DW). The Ground granulated Blast furnace slag (GGBS) is an industrial waste and a pozzolanic material that has received considerable attention in both research and application. It is a byproduct of the steel industry. Here the cement is replaced by GGBS in different percentages varying from 0%, 10%, 20%, 30%, 40%, 50%and 60% with Demolishing Waste of 30% constant as a replacement of coarse aggregate. The various mechanical properties and durability test on the concrete specimens were obtained from the partial replacement of cement with GGBS and coarse aggregate with demolishing waste. Keywords- GGBS, durability, demolishing waste.
