Advances on the Use of Geopolymer Recycled Aggregate Concrete in Construction

Abstract

Geopolymer cement is made up of waste materials, an efficient alternative to ordinary cement in order to reduce the emission of carbon dioxide. The use of geopolymer recycled aggregate concrete (GRAC) in structural elements has been an object of recent several experimental research in which the behaviour of either the material or structural element was investigated. A review paper will be done critically to compile the present research on the use of GRAC in construction. It will cover the effect of different materials composition in GRAC and the factors affecting its strength focusing on recycled aggregate’s replacement ratio. The problems related to the strength of GRAC structural members, their tensile and flexural behaviour will also be addressed. It will also help in finding the future prospects of the use of GRAC in construction.
