Abstract
The rheological and mechanical properties of high-strength anchorage grouting materials for highway slope were investigated to optimize the mix proportion. The experimental results showed that the optimized mix proportion of high-strength anchorage grouting material (HAGM) was C3 (FA:SP:SF= 1:2:2; AG1:AG2=3:7 and 0.03% FC), which is agreement with the limitation of JCT 986–2005. Moreover, the XRD and FTIR results showed the addition of expansive components was in favor of the formation of ettringite. The intensity of AFt peak of the samples increased with the increasing of hydration time.
