摘要
近几年来,随着泵送混凝土的普及使用,工程中泵送混凝土塑性裂缝也随之出现,本文结合工程实例阐述了泵送混凝土塑性裂缝的产生机理,分析了混凝土塑性裂缝产生的条件,指出此种类型裂缝对混凝土结构的使用性及耐久性产生影响的事实,并提出对此种类型裂缝的防治方法。
Recent years, with the popularity of the use of pumping concrete, practical projects in the pump concrete plastic cracks also will be there; the paper expounds the mechanism and condition of plastic cracks, points out its damage to the concrete Structures and puts forwards prevention methods.
