摘要
介绍了应用高性能混凝土施工遇到的问题,主要有水泥与高效减水剂之间的相容性、新拌混凝土的泌水、粗集料选择与配合比设计方法等问题,分析了产生这些问题的原因,提出了对策,并通过试验分析,对提高高性能混凝土外观质量提出了建议。
The article describes the problems in the application of high-performance concrete, mainly including compatibility between cement and super-plasticizer, the bleeding of just mixed concrete, the selection of coarse aggregate and the designing methods of mixing proportion. It simultaneously analyzes the causes of these problems and solutions. Based on the experiment and analysis, it makes suggestions to enhance the appearance and quality of high-performance concrete.
