Experimental Investigation on Partial Replacement of Cement by GGBS

The production of cement results in emission of many greenhouse gases in atmosphere, which are responding properties for global warming.The waste material having cementing properties which can be added in cement concrete as partial replacement of cement, without compromising on its strength and durability, which will results in decrease of cement production thus reduction in emission in greenhouse gases.The ground granulated blast furnace slag (GGBS) is a waste product from the iron manufacturing industry, which may be used as partial replacement of cement in concrete due to its inherent cementing properties.In this study Ground Granulated Blast Furnace Slag (GGBS) was partially replaced as 0%, 10%, 20%, 30%, and 40% in place of cement in concrete.Concrete are made for M -30 mix and the cubes, cylinders and prisms are casted for 7, 14 & 28 days of age in order to find out the optimum percentage of replacement of GGBS in concrete.
