摘要
混凝土作为一种多相复合基材料,具有较高弹性模量和抗压强度及较低的抗拉强度,在受约束作用下少许收缩就会产生裂缝,裂缝产生的材性原因较多。当裂缝产生时,为保证结构的耐久性,就需要修补,修补材料的材性和基性材料的材性需要有效协调,以免产生二次裂缝。
Concrete, a kind of muti-phase material, should be possessed of higher elastic modulus and compressive strength and lower tensile strength. The concrete materials with a little contraction are likely to crack when acted on by the restraining pressure there are a number of reasons accounting for these cracks, when cracks occur, the mending job is needed to ensure the durability of structures. Meanwhile, there need to be an effective co-ordination of the attributes of repairing materials and original materials incase cracks should occur once more.
