Factors affect the bond strength of Geopolymer repair material: Review

Abstract

One of the most important construction activities worldwide is the repair and rehabilitation of damaged concrete structures. Many concrete structures are decaying, sometimes early, and need remediation to restore their protection and serviceability. As a result, in recent years the need for repair and safety has increased dramatically. This paper reviewed some studies about the potential for geopolymer to be used as a repair material and highlighted the main factors effect bond strength between GP and OPCC. The bond strength of GP was assessed using splitting tensile test and slant shear test. The results of bond strength indicated that this form of GP could be employed as a potential repair material..
