桩基工程中的自密实混凝土应用

Application of self-compacting concrete in pile foundation engineering

针对钻孔灌注桩水下混凝土浇筑无法按常规振捣密实的难点,提出了采用自密实混凝土的解决方法,并研究了自密实混凝土的性能、配比设计及施工方法,从而推广自密实混凝土在桩基工程中的应用。

According to the difficulty of concrete pouring in water in bored pile foundation engineering, self-compacting concrete is proposed to use to set the problem. And it analyzes the performance, ratio design, construction method of self-compacting concrete, so as to promote the application of self-compacting concrete in pile foundation engineering.
