Bond strength between the reinforcement rebar and geopolymer concrete: A review.

This study adopted a review of bond strength and discussed the research in geopolymer concrete. Studies and research on the structural properties of geopolymer concrete are relatively limited in comparison to ordinary concrete. As a result, this review covers the majority of the research on the Bond Strength of geopolymer concrete, cementitious materials and curing regimes. Many investigations on several researchers have worked on geopolymer concrete. Geopolymer Concrete has the advantage of using extra cementitious materials in conjunction with alkali-activated solutions to substitute cement (The reaction of geopolymer concrete materials is activates by it). After doing a study on previous researches, the output of reviewed papers explained that the pozzolanic materials and curing conditions are affected in the clear for the bond strength; it has been discovered that geopolymeric concrete made from fly ash performs better than Conventional Concrete based on Portland cement in terms of mechanical properties, withstanding high temperature, and preservation of fundamental physical characteristics including permeability and water absorption. Whereas few studies exanimated the effect of fiber on bond strength. [ABSTRACT FROM AUTHOR]
