Construction and Demolition Waste-based Geopolymer Concrete: A Brief Review

Abstract

Cement concrete and other cement-based composites find wide application in the construction industry. The manufacturing of cement releases a large amount of CO2, so the use of cement has become a major area of environmental concern. Attempts have been made to minimize the quantity of cement in concrete by replacing it with supplementary cementitious materials. Geopolymer concrete is one of those potential candidates for alternative cementitious materials. In today’s world, the production of Construction and Demolition (C&D) wastes has been increased worldwide which finds no suitable disposal and cannot be used in ordinary concrete due to potential deterioration of concrete quality. However, C&D waste can be safely used with geopolymer concrete with and without the usage of Supplementary Cementitious Materials (SCMs) and play a major role in improving the strength and durability properties of concrete.
