预防混凝土裂缝的几项对策

Several Measures for Preventing the Fractures of the Concrete

分析了混凝土结构产生塑性收缩裂缝、沉降裂缝、温度裂缝的危害以及产生裂缝的原因,从材料组成设计(配合比)和施工工艺方面提出了应采取的预防对策。

This paper analyzes on the harms and causes of the plastic shrinkage fracture, settlement fracture and temperature fracture of the concrete structure, and puts forward some preventive measures that should be taken from aspects of the design of the materials components（mixture ratio） and the construction techniques.
