In order to improve the durability of coral aggregate seawater concrete (CASC) structures, the influences of exposure time, concrete strength, concrete cover thickness, steel type and inhibitor addition method on the steel corrosion behavior of CASC were investigated and the law of steel corrosion in CASC was obtained. This showed that the steel anticorrosion capacity of CASC structures in the marine environment is 316 stainless steel > new organic coated steel > common steel; this suggests common steel should not be used in CASC structures. In addition, both traditional addition and preabsorption of an amino alcohol inhibitor (AA) result in the enhancement of the anticorrosion capacity of CASC. Moreover, the effect of anticorrosion by preabsorption is better than by traditional addition. Therefore, for CASC structures in marine engineering, it is recommended to choose new organic coating steel, that the thickness of the concrete cover be at least 55 mm, and that the concrete strength reach C50 and preabsorption of AA. In this way, the durability of a CASC structure can be improved and its effective service life can be prolonged.

珊瑚骨料海水混凝土中钢腐蚀的电化学研究。

为了提高珊瑚骨海水混凝土结构的耐久性，研究了暴露时间，混凝土强度，混凝土表皮厚度，钢种和添加抑制剂的方式对CASC钢腐蚀行为的影响，并研究了钢腐蚀规律。在CASC中获得。这表明CASC结构在海洋环境中的耐腐蚀能力为316不锈钢>新型有机涂层钢>普通钢。这表明普通钢不应用于CASC结构。另外，传统的添加和氨基醇抑制剂（AA）的预吸收都可以增强CASC的防腐能力。而且，预吸收的防腐蚀效果比传统添加的防腐蚀效果更好。因此，对于海洋工程中的CASC结构，建议选择新的有机涂层钢，混凝土覆盖层的厚度至少为55 mm，混凝土强度达到C50并预先吸收AA。以此方式，可以改善CASC结构的耐久性，并且可以延长其有效使用寿命。
