耐酸性混凝土在弱酸性地基中的工程应用

Applications of Acid-resistant Concrete in Weak-acidic Foundation

针对重庆江北区建新西路三期工程(天原段)建设中所遇到的弱酸性地基处理难题,通过试验研究和工程检测,选择配制耐弱酸性混凝土的地方材质,对耐弱酸性混凝土进行试配和优化,确定设计配合比,使所配制的耐弱酸混凝土具有良好的性能,满足工程的需要,为重庆市弱酸性地基环境中耐酸混凝土施工应用探索出了一条新路。

According to the problem of foundation treatment in third phase project of Jianxin west road, through experimental study and engineering test, selected local materials which suit for acid-resistant concrete, made trial-mixture and optimization for acid-resistant concrete, determined concrete mix. Experiment results show that acid-resistant concrete had a good performance and meet the needs of project. It explored a new way to acid-resis- tant concrete construction for weak-acidic foundation environment in Chongqing.
