探讨了混凝土保护层的作用机理及保护层开裂的原因,并通过计算,分析了影响保护层最大裂缝宽度的因素,指出采用相对合理的保护层厚度能够在一定程度上控制和减小混凝土裂缝宽度。
The action mechanism of concrete protective layer and the reason of protective layer cracking were discussed. The factors affecting the maximum crack width of protective layer were calculated and analyzed. It is pointed out that using relatively reasonable thickness of protective layer can control and reduce the width of concrete crack .
