The Performance of Geopolymer Concrete Utilizing Wastes as Binder
Utilizing wastes at present is of utmost importance since it not only leads to the reduction in environmental load and reduction of carbon footprint but also reduction in waste management cost. Geopolymer concrete has been developed as a substitute to conventional cement-concrete where alkali activators react with the binder along with fine and coarse aggregates. The binder for geopolymer concrete can be any wastes which are rich in silica and alumina that will collectively lead to the reduction in the concrete pollution and enhancement of its properties. The objective of this paper is to review the mechanical performance of geopolymer concrete utilizing wastes like fly ash, metakaolin, rice husk ash, palm oil fuel ash, red mud, ferrochrome ash, and so on as binder. It is observed that slag-based geopolymer concrete can be cured in ambient temperature but for the other binder materials, elevated curing temperature is required to attain the target strength. The mechanical properties (like compressive, split tensile, flexural properties) of the geopolymer concrete utilizing fly ash and slags as binder have shown to provide more strength than other binder combinations, and therefore prove to be a better replacement to the conventional cement-concrete.
