摘要
C50及以上强度的混凝土对桥梁施工有着至关重要的作用。原材料选择主要包括集料、水泥和外加剂的选择。C50混凝土配合比设计需计算C50混凝土比配合比并确定试拌混凝土基准配合比。
Concrete with the strength of C50 and above is of great importance to bridge construction. Selec- tion of raw materials mainly includes aggregate, cement and admixture. Designing C50 mix ratio needs to calcu- late the mix ratio and determine the base mix ration of testing concrete.
