Study of various properties of geopolymer concrete-A review

Cement, being a key material of concrete, experiencing a rise in global demand. It has a massive carbon footprint having a contribution of about 8% to the global CO2 emissions. Geopolymer concrete has a huge potential to replace ordinary Portland concrete. An overview of geopolymer concrete is presented in this paper. Discussion includes constituents and their mix proportions, mechanical and rheological properties of geopolymer concrete(GPC), the interfacial transition zone(ITZ), bond strength for steel reinforcement. Along with the change in properties with different blends of GGBS in fly ash-based GPC, the effects of constituents on the properties are outlined. This paper also highlighted comparisons between ordinary Portland cement concrete(OPCC) and GPC based on the work of different researchers. GPC has better mechanical properties and has a lower carbon footprint making it a potential material for the construction sector in the near future. (c) 2020 Elsevier Ltd. All rights reserved.
