Abstract:Concrete made with Portland cement has been a popular construction material in the world for the past 170 years or more .The major causes in our construction industry is emission of carbon dioxide during cement manufacture and solid waste disposal problem. However, reduction of cement consumption by partial replacement of ordinary Portland cement by industrial wastes or by-products. Ground granulated blast furnace slag is by-product and is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. These materials called pozzalonas) when combined with calcium hydroxide, exhibits cementitious properties.The study has been made to evaluate the effect on mechanical and durability properties of M20 grade concrete made with replacement of cement with ground granulated blast furnace slag(GGBS),(20%,40%and60%) by weight.For each set of GGBS, mechanical properties were studied by performing compression test for cubes, Flexure test for beams and split tensile test for cylinders and durability properties were studied by performing sulphate attack and seawater test cube .

Keywords: Ground granulated blast furnace slag (GGBS),sea water ,sulphate attack,durability.
