中文摘要：

文章对矿用补偿收缩钢纤维混凝土在不同侵蚀龄期下的抗硫酸盐侵蚀压拉性能进行研究。结果表明,在膨胀剂掺量为8%、钢纤维体积率为1.2%时其效果最佳。在硫酸盐溶液中侵蚀100d,其抗压强度和抗拉强度相对未侵蚀的基准混凝土分别提高了36.2%、4.52%;侵蚀200d的抗压强度和抗拉强度相对侵蚀100d分别下降了2.16%、2.08%。

英文摘要：

The paper had a study on the compressive and tensile performances of the mine shrinkage compensation steel fiber concrete under the sulphate erosion resistance with the different erosion period.The results showed that when the mixing ratio of the swelling agent was 8% and the steel fiber volume rate was 1.2%,the steel fiber concrete would have the best effect.With the 100 days erosion in the sulphate solution,the compressive strength and the tensile strength of the mine shrinkage compensation steel fiber concrete could be improved by 36.2% and 4.52% than the non erosion basic concrete individually.With the 200 days erosion in the sulphate solution,the compressive strength and tensile strength would be reduced by 2.16% and 2.08% lower than the 100 days erosion concrete individually.
