Abstract:
Compressive strength and splitting tensile strength of the shrinkage-compensating steel fiber reinforced shotcrete with steel fiber and different dosages of expansive agents are studied.The results show that,with the dosage of expansive agents increaseing,the reinforcement effect of the steel fiber on the shrinkage-compensating steel fiber reinforced shotcrete becomes more obvious,but this reinforcement effect will be significantly reduced when the dosage of expansive agents beyonds a certain limit.With the steel fiber volume content of 0 and 1.2% for shrinkage-compensating steel fiber reinforced shotcrete,the best match dosages of expansive agents are 6% and 8%.
