中文摘要：

对钢纤维和不同膨胀剂掺量下的喷射补偿收缩钢纤维混凝土抗压强度和劈裂抗拉强度进行了试验研究。结果表明,随着膨胀剂掺量的增加,钢纤维对喷射补偿收缩钢纤维混凝土的增强作用越明显,但膨胀剂掺量超过一定限度会明显降低这种增强作用,钢纤维体积率掺量为0和1.2%的喷射补偿收缩钢纤维混凝土中,膨胀剂的最佳匹配掺量分别为6%和8%。

英文摘要：

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%.
