摘要
对不同技术条件的钢筋混凝土试件进行长期的海洋暴露腐蚀试验,以了解其服役特性,为钢筋混凝土结构的耐久性设计提供依据。近7年的暴露结果表明:在混凝土中掺加高炉矿渣等活性掺合料,能大大降低氯离子渗透速率,提高钢筋混凝土的耐久性。
Corrosion of steel reinforcements is one of the major problems with respect to durability of reinforced concrete structures exposed to marine environment. This paper aims at evaluating the effect of various concrete parameters on durability in coastal exposure condition. 7-year exposure results have demonstrated the substantial benefits of reducing chloride ingress and enhancing rebar anti-corrosion performance by using fly ash or granulated blast-furnace slag.
