摘要：暴露在海水中的混凝土会被盐类溶液--主要是氯化钠和硫酸镁--浸湿。对混凝土的损坏，如果发生的话，通常是由于没有在混凝土施工中使用良好的做法造成的，而且往往是冻结和融化或潮湿和干燥的结果，其程度与海水本身的影响一样多，甚至更多。硫酸镁可侵蚀硬化波特兰水泥浆体的大部分成分，特别是铝酸盐成分；氯化物可促进钢的腐蚀；碱可参与碱-集料反应。
Abstract : Concrete exposed to sea water is wetted by a solution of salts-- principally sodium chloride and magnesium sulfate. Damage to concrete, if it occurs, usually results from failure to use good practices in concrete construction, and often is the result of freezing and thawing or wetting and drying as much as or more than the results of the effects of sea water as such. Magnesium sulfate may attack most, if not all, of the constituents of hardened portland cement paste, especially the aluminate constituent; chlorides may promote corrosion of steel; and alkalies may participate in alkali-aggregate reaction.
