| 摘 要： | 从混凝土自身组成出发，研究了水泥强度等级、掺合料、纤维对混凝土损伤自愈合性能的影响．结果表明：选用低强度等级水泥、用粉煤灰部分取代水泥以及加入纤维都可以在一定程度上提高混凝土的自愈合效果．另外，对混凝土自愈合机制和自愈合效果进行了分析和探讨．

| Abstract: | Through further hydration of cementitious particles, concrete has self-healing capability after being damaged. To study the influence of concrete components on self-healing performance, several factors such as grade of cement, fly ash, and carbon fibers, are considered. The test results show that low grade cement, replacement of cement by fly ash, and adding some carbon fibers are all helpful in improving the self-healing performance of concrete. Furthermore, the mechanism and the effect of concrete self-healing performance are analyzed and discussed. |

| Keywords: | self-healing concrete cement grade supplementary cementitious material fiber |
