Abstract
Geopolymer concrete (GPC) has been researched during the past few decades as a viable sustainable construction material, which can minimise CO2 emission for its use of industrial by-products. Past research on GPC shows that GPC is best suited for structural application with workable slump and strength as compared to ordinary Portland cement concrete (OPCC). The microstructure of GPC and OPCC has been investigated to understand its influence on engineering properties. It has been observed that GPC contained more amorphous phases, less porosity and more pores in the mesopores range than OPCC. Review of the literature revealed that the production of geopolymer concrete requires great care and correct material compositions. During the activation process in making the geopolymer, high alkalinity also requires safety risk and enhanced energy consumption and generation of greenhouse gases. Furthermore, the production of GPC is also affected by the curing time and curing temperature. Few studies have also been carried out to observe the effect of curing temperature on the polymerisation reaction of GPC.
