Abstract: The major problem the world is facing today is the environmental pollution. In the construction industry mainly the production of Portland cement will causes the emission of pollutants results in environmental pollution. The carbon dioxide produced by cement industries causes environmental pollution and global warming. In 1000Kg of cement manufacturing processes approximately 900Kg of CO2 is emitted. In order to reduce the impact of cement production on atmosphere, wastes by products are used as admixture in this study, so that environmental pollution and natural resources consumption is reduced.In the present study wood ash is varied up to 20% (5%, 10%, 15% and 20%) and GGBS is added to optimum wood ash content cement concrete from 10% to 30% (10%, 20% and 30%).These two wastes are used as a partial replacement of cement and various properties like Compressive strength, Split tensile strength and Shear strength were determined.

Keywords: Wood ash, GGBS, Concrete, aggregates, Compressive strength, Split tensile strength, Shear strength test and Fineness modulus
