钢筋混凝土本来是相当耐久的材料,但是在海洋环境,尤其在浪溅区,由于氯盐的积聚和合适的通氧条件,常常因钢筋锈蚀而导致结构的损坏。我国很多海港码头就是这样破坏的(参见《水运工程》1982年2期〈华南沿海港口调查〉一文)。因此,如何提高海洋工程耐久性,防止钢筋混凝土的锈蚀损坏日益引起了人们的重视。日本和英国是 Reinforced concrete was originally a fairly durable material, but in the marine environment, especially in splashed areas, structural damage is often caused by steel corrosion due to the accumulation of chloride salts and the proper aeration conditions. Such is the case with many of our harbor harbors (see Water Transport Project, 1982, No. 2, “South China Coastal Harbor Survey”). Therefore, how to improve the durability of marine engineering and prevent the corrosion damage of reinforced concrete has aroused people’s attention day by day. Japan and Britain are
