Rubberized Geopolymer Mortar and Concrete: A Comprehensive Review.

Abstract

In many crucial structural applications, a material’s ability to withstand impact is of the utmost importance. The use of crumb rubber particles as a partial replacement of natural aggregates forms rubberized geopolymer concrete (RuGPC), which is found to have great impact resistance and energy absorption capacity. Geopolymer paste and natural aggregates alone are weak in handling the impact loads. The field of Civil engineering has been looking into ways for the last few years to use solid waste and ecologically friendly raw materials as components of concrete in building to embrace sustainability. Greenhouse gas emissions from cement manufacturing and the depletion of natural aggregates are two major issues the construction industry is currently experiencing. RuGPC, which combines the benefits of geopolymer concrete (GPC) and rubberized concrete to create a practical, sustainable building material, has been a hot topic for the past few years. In this paper, the fresh properties, strength and durability characteristics, mixing procedure and curing properties, dynamic and impact properties, microstructures and thermal properties of rubberized geopolymer mortar and concrete are comprehensively reviewed.
