C30水下防腐蚀混凝土配合比设计及应用

Design and Application of C30 Underwater Anti-corrosion Concrete Mix

结构防腐主要从混凝土内部阐述其腐蚀性,并通过掺入外加剂进行有机补偿。以天津海河开启桥C30水下防腐蚀混凝土配比设计结果及施工经验,阐述了防腐蚀混凝土的配合比设计、硫酸盐防腐机理及混凝土的防腐性能测定方法。

It describes structure antisepsis mainly from the concrete internal structure Through adding admixtures,its antisepsis can be compensated organically.Based on the Haihe river open structure bridge in Tianjin C30 underwater corrosion resistant concrete ratio design and the construction experience,it describes the ratio design of corrosion resistant concrete,sulfate anticorrosive mechanism and methods for the determination of the anticorrosion performance of concrete.
