Evaluation of Geopolymer Concrete with Crumb Rubber: A Review
Cement is a major source of CO2 emissions, which has negative consequences for the environment. Geopolymer concrete is found to be a promising substitute for Portland cement. Rubberized concrete provides a suitable way for tire waste disposal by replacing aggregates in concrete with crumb rubber. There have been several studies conducted on both geopolymer concrete as well as rubberized concrete. A combination of both these to form a rubberized geopolymer concrete promises to be sustainable construction material, which has been a hot topic among researchers recently. Important aspects such as constituents, mixing and curing aspects, physical and fresh properties, durability properties, and mechanical properties of RuGPC conducted on previous works are reviewed. The effect of crumb rubber addition, alkali, binder type, the alkali to binder ratio, and curing type on the above-mentioned aspects are reviewed. From the review of literature, it was found that durability in terms of wear depth is only 0.8 mm even with 30% replacement of fine aggregates by crumb rubber. New treatments that can be given to crumb rubber for improving the bonding between geopolymer matrix and rubber is also highlighted in this work.
