从海砂、珊瑚礁及海水的特性进行分析,对海砂、珊瑚礁及海水中有害化学组分对海工混凝土的耐久性的影响进行了剖析,探讨了提高混凝土保护层厚度、特种钢筋、阴极保护技术和采用钢筋阻锈剂技术措施在该类型混凝土中应用的可行性,并结合工程案例展望了该类混凝土的应用前景及存在的问题。
Analyzed the characteristics of sea sand, coral reefs and sea, and the effect of harmful chemical composition in sea sand, coral reefs and sea water on the durability of marine concrete were also analyzed. The feasibility of technical measures, such as improve con- crete protective layer thickness, special steel, cathodes protection technology and corrosion inhibitor adopt, applied in this type of con- crete were investigated.Application foreground and problems of this kind of concrete were prospected combined with project cases.
