Chemical Resistance of Cement Concrete Partially Replaced with GGBFS and Fully Replaced with M-Sand

The innovations in the production of concrete opens the door for using different kinds of materials considered as industrial waste and hazardous in nature. Using such industrial waste by-product material for making concrete should yield better strength and durability than conventional concrete. The main purpose of this study is to identify the chemical resistance of the cement concrete developed using 40% of Ground Granulated Blast Furnace Slag (GGBFS) as partial replacement for ordinary Portland cement and 100% M-Sand as full replacement for river sand. The chemical resistance of concrete such as acid resistance and sulphate resistance are found by casting and immersing 150 X 150 X 150 mm concrete cube specimen in the chemical solution for a period of 56 days. Four kind of specimens are cast such as conventional concrete cubes, concrete with M-sand, Concrete with 40% GGBFS and river sand and concrete with 40% GGBFS and M-Sand. The concrete with 40% GGBFS and M-Sand showed better chemical resistance than all other concrete cube specimens. From the results, the use of concrete with 40% GGBFS is appreciated and it will be suitable for practical applications. The use of M-Sand and 40% GGBFS improved the compressive strength and the chemical resistance of concrete cube specimens.
