摘　　要：通过普通混凝土和钢纤维混凝土对比试验,来探讨不同养护条件及龄期对钢纤维混凝土强度的影响。试验结果表明,钢纤维混凝土强度随龄期的变化规律与普通混凝土基本相同,养护条件对混凝土早期强度的影响很显著。建议实际工程施工中加强对混凝土的早期养护,同时对于施工期较长的水利及大型土木工程,在保证良好养护的前提下,可考虑利用混凝土的后期强度。Based on the test results of concrete and steel fiber reinforced concrete, the influence of maintain condition to the strength of steel fiber reinforced concrete is discussed. The results show that: the change rule of the strength of steel fiber reinforced concrete is simile to the ordinaire concrete, and the influence of maintain condition to the strength of steel fiber reinforced concrete and ordinaire concrete is vary evident. The engineering suggestions are put forwarded.
