A STUDY ON RECYCLING AND RESUSE OF MUNICIPAL SOLID WASTE IN CONSTRUCTION INDUSTRY

Abstract

The municipal solid waste incineration ash reduces are worldwide studied topic over the last decades, so that utilize the municipal solid waste is the one of the possibilities is to use MSW ash in concrete production as it is done the bottom ash features the most convenient composition in concrete and it is available in highest amounts among the MSW ashes the bottom ash was used as partial replacement of cement in concrete strength has to find, if the prepared concrete will get sufficient strength or not. The behavior of concrete with the bottom ash is differed from the control material due to presence of sulphates and chlorides. This project about the feasibility of using municipal solid waste ash as a replacement of cement in M25 grade concrete. The municipal solid waste ash proportion utilized here is 0%, 5%, 10%, 15% and 20% by the weight of cement, weight of fine aggregate, coarse aggregate and water cement ratio is kept constant. The investigation concentrated on the test of Harden and Fresh properties of concrete. On the basis of experimental results of this investigation, it is concluded that the Optimum percentage of MSW ash replacement of cement in the concrete is 5%.
