In this paper, a high-performance geopolymer grouting material based on slag and fly ash was developed and the properties were investigated. The fluidity, setting time, compressive strength, water resistance and drying shrinkage were studied to evaluate the workability and mechanical properties of geopolymer grouting material (GGM). X-ray diffraction (XRD) and scanning electron microscope (SEM) were used to analyze the microstructural performance of GGM. The results show that the concentration of alkaline activator and slag content plays a significant role in properties of GGM and the optimum formula has been obtained. In the course of the study, the effect of concentration of alkaline activator and the content of slag on the workability and mechanical performance of GGM is different. All properties of geopolymer were considered comprehensively, the slag content and concentration of alkaline activator were 70% and 37%, which indicated that the geopolymer grouting material made from slag and fly ash could meet the requirements of concrete reinforcement well and was friendly to the environment.
