Experimental Study on the Effect of Recycled Aggregate and GGBS on Flexural Behaviour of Reinforced Concrete Beam

Globally, the concrete industry consumes large quantities of natural resources, which are becoming insufficient to meet the increasing demands. Cement and aggregates are major constituents of concrete. Utilisation of waste materials in concrete instead of raw materials reduces environmental pollution. Ground-granulated blast-furnace slag (GGBS) is a by-product of steel industry. It has cementatious property. Recycled aggregates are obtained from demolishing waste. By using recycled concrete aggregate and GGBS in concrete we can reduce environmental problem to some extent. This experimental study evaluate the effective utilisation of GGBS and recycled aggregate in concrete. In this study GGBS is used as partial replacement for cement and recycled aggregate as partial replacement for coarse aggregate.
