Influence of industrial by-products on the behavior of geopolymer concrete for sustainable development

Abstract

Carbon dioxideemission in cement industries is a great concern for environment, which is increasing day by day. Therefore, it is very essential to find a possible material that can be used as a replacement of cement. Geopolymer concrete is a kind of inorganic concrete elucidating the formal usage of industrial and natural waste in either single or combined form. Geopolymers are amorphous covalently bonded by a 3D network of inorganic molecules of aluminosilicate material. The formation of geopolymer concrete is greatly influenced by several factors such as binder chemical reaction, curing temperature/period, molarity of the solution, and rate of polymerization. The curing temperature helps in deciding the properties of geopolymer. Performance variables for geopolymer concrete such as selection of alkaline binder with pozzolana (Fly ash, slag, silica fume etc.) and interrelationship of GPC, reinforcing agent in geopolymer concrete with components responsible for durability are summarized in detail. The durability of concrete is reviewed with structure with shrinkage-resistant, resistant to sulfate attack, and consequences of carbonation. The various consequences of corrosion are also summarized in last of present review paper. Different research findings in this paper proves successfully that geopolymer is better construction material as compare to cement-based concrete.
