摘　　要：本文采用在混凝土中掺入补偿收缩剂和有机纤维复合改性的方式,通过试验得到改性后面板混凝土的力学强度、干缩变形以及自身体积变形性能等;结果表明,纤维和补偿收缩剂复合改性技术可以显著地降低混凝土的收缩变形,提高抗裂性能。In this article, face slab concrete incorporated with expansive agent and polypropylene fiber has been proportioned. The strength, drying shrinkage and autogenous volume deformation of the modified concrete was measured by certain tests. Test results indicated that the technology of concrete incorporated with expansive agent and polypropylene fiber can decrease the shrinkage significantly, and increase the ability of crack resistance of concrete, too.
