混凝土耐久性由于劣化速度过快,越来越被社会各界关注。本文通过对混凝土劣化机理和混凝土裂缝产生原因的分析,指出混凝土的耐久性和混凝土的抗渗性密切相关,而在施工过程中减小混凝土内部的内应力是控制裂缝、提高混凝土耐久性的根本。同时,论述了控制混凝土裂缝的思路和做法,以及目前在工程施工中与混凝土耐久性相关的质量通病。
Due to the deterioration of concrete durability too fast, more and more attention by the community. In this paper, by analyzing the mechanism of concrete deterioration and the causes of concrete cracks, it is pointed out that the durability of concrete is closely related to the impermeability of concrete. Reducing the internal stress of concrete during the construction process is the basis of controlling cracks and improving the durability of concrete . At the same time, the ideas and practices of controlling concrete cracks are discussed, and the common faults of quality related to durability of concrete currently used in engineering construction are discussed.
