摘要
研究了C50清水混凝土配合比设计技术要点以及生产组织和混凝土现场浇注施工、养护过程中的关键措施。通过优选水泥、粉煤灰和微珠,调整粉料比例以及砂率、用水量,遴选高性能外加剂,配制出了具有适宜粘聚性和工作性能的清水混凝土。
The key technology of mix proportion design of fair-faced concrete is studied. At the same time, the producing organization, casting process and curing technology in situ are also presented. The fair-faced concrete with appropriate cohesiveness and workability is prepared by means of optimizing cement, fly ash, micro-sphere, high performance admixture, binder proportion, sand ratio and unit water consuption.
