Anti-cracking Measures for Pavement Concrete on Roller-compacted Concrete Gravity Dam

介绍了新疆某碾压混凝土重力坝坝顶铺装层混凝土施工中采取的混凝土防裂措施,例如采用调整混凝土配合比、设置隔离层、适当分块、加强养护及在混凝土中添加纤维素纤维等,这些措施有效地减少了混凝土裂缝,对夏季高温、冬季严寒、风大、干燥少雨等恶劣气候条件下混凝土防裂具有指导意义。

The anti--cracking measures for pavement concrete on a roller-compacted concrete gravity dam in Xingjiang are introduced, including adjusting concrete mix ratio, setting isolation layers, separating concrete block, strengthening concrete curing and adding cellulosic fibers. These measures effectively decrease the cracking of pavement concrete. These measures provide a reference to the anti-cracking of concrete pouring in adverse weather conditions of very high temperature in summer, very low temperature in winter, strong wind and special dry.
