【 摘 要 】

To investigate the influence of water-cement ratio on the fluidity and mechanical strength of geopolymer grouting materials, the change of fluidity, compressive strength and flexural strength of road geopolymer grouting material with different water-cement ratio were tested. The results showed that the fluidity of geopolymer grouting material was enhanced while the compressive and flexural strength decreased with the increase of water-cement ratio. The optimum value of water-cement ratio was in range (0.39-0.42). The road geopolymer grouting material had the better fluidity and the strength requirement of reinforcement if the main constituent materials was not changed.
