在基体对面层现浇混凝土变形约束的条件下。温度、湿度变形引起的收缩应力是码头面层裂缝产生的主要原因。在码头面层中引入补偿收缩混凝土,减少基体对面层的约束,可以做到面层少出现或不出现裂缝。
Under the condition that the deformation of cast-in-place concrete on the opposite side of the substrate is restrained. Shrinkage stress caused by temperature and humidity deformation is the main reason for cracks in the surface of the wharf. The introduction of compensation in the pier surface shrinkage of concrete to reduce the constraints of the substrate on the surface, you can do with the surface layer appears or not cracks.
