Influence of industrial by-products on the behavior of geopolymer concrete forsustainable development
Carbon dioxide emission 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 concreteis a kind of inorganic concrete elucidating the formal usage of industrial and natural waste in either single or combinedform. 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, curingtemperature/period, molarity of the solution, and rate of polymerization. The curing temperature helps in deciding theproperties of geopolymer. Performance variables for geopolymer concrete such as selection of alkaline binder withpozzolana (Fly ash, slag, silica fume etc.) and interrelationship of GPC, reinforcing agent in geopolymer concrete withcomponents responsible for durability are summarized in detail. The durability of concrete is reviewed with structure withshrinkage-resistant, resistant to sulfate attack, and consequences of carbonation. The various consequences of corrosion arealso summarized in last of present review paper. Different research findings in this paper proves successfully thatgeopolymer is better construction material as compare to cement-based concrete.
