Influence of the Additives on Its Rheology Properties of the Shotcrete

摘要：

　　This work investigated the rheological characterization of alumina-spinel shotcretes during the shearing cycles.The results of rheological test indicated that the hydration of calcium aluminate cement in the matrix made the unloading curve beyond the loading curve.This phenomenon demonstrated that this shotcrete was so dilatant that could block the pipe during pumping.Meanwhile,the influence of silica fume and retarder on the rheology in the shearing cycles was investigated.
