混凝土裂缝的自愈性修复

Self-healing repair of concrete cracks

混凝土作为应用最为广泛和不可或缺的建筑材料,其构件中不可避免产生的微裂纹及裂缝,是由其自身的物理力学性质和外界环境条件所制约的。为此,已有如灌浆缝合、钻孔填塞等多种传统方法在实施修复。本文对当今已成热点的混凝土构件的自愈性修复技术,进行简要的综述。

Concrete is the most widely used and indispensable building materials.The microcracks and fissures in the concrete constructional members are inevitably emerged due to their own physical and mechanical properties and the impact of external environmental conditions.For that reason,many traditional methods of repairing have been presented,such as joint grouting,borehole and stamming,etc.In this paper,the advances of studies on the self-healing repair of concrete cracks,which has become a hot point at present,was reviewed briefly.
