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 con- crete by replacing it with supplementary cementitious materials. Geopolymer concrete is one of those potential candidates for alternative cementitious mate- rials. In today’s world, the production of Construction and Demolition (C&D) wastes has been increased worldwide which finds no suitable disposal and can- not 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.
