补偿收缩混凝土工程应用注意事项

Announcement of Shrinkage Compensating Concrete Engineering Application

补偿收缩混凝土可以显著提高混凝土结构的抗裂防渗效果。本文介绍了补偿收缩混凝土工程应用中的一些注意事项,如膨胀剂的选择、后浇带过早拆除支撑、施工冷缝、振捣不到位、养护不当引起的塑性裂缝以及踩踏造成的开裂。针对上述事项,加强施工管理,便于改善补偿收缩混凝土应用质量。

Shrinkage compensating concrete can improve the crack resistance and anti-seepage effect of concrete st4 ructure. This paper introduce the matters should be noticed, such as the selection of expansive agent, the untimely support removal of post-pouring joint, construction joint, insufficient vibrating, plastic shrinkage crack due to improper maintenance, and crack induced by caterpom. In the view of the above question, the engineering application quality of shrinkage compensating concrete by strengthening the construction management.
