混凝土中钢筋的防蚀方法主要有下列几利: (1)采用较厚的混凝土保护层; (2)采用优质密实的混凝土; (3)在混凝土表面涂刷防水涂料; (4)在混凝土中掺阻锈剂; (5)对水下部位的构筑物进行阴极保护; (6)钢筋采用涂层保护; (7)采用镀锌、镀镉或镀铝钢筋等。其中,镀锌钢筋的防蚀效果较好,最适于海洋环境中使用。本文将综述混凝土构筑物中钢筋的锈蚀、钢筋的镀锌方法、镀锌钢筋的各种性能及其使用方法。一、混凝土中祼钢筋的锈蚀海洋环境中的钢筋混凝土构筑物,常常
Anti-corrosion methods for reinforcement in concrete include the following advantages: (1) Thicker concrete protection layer; (2) High-quality and dense concrete; (3) Waterproof coating on concrete surface; (4) In concrete (5) Cathodic protection of structures at the underwater site; (6) Reinforced with steel coating; (7) Galvanized, cadmium plated, or aluminized steel bars. Among them, galvanized steel has a good anti-corrosion effect and is most suitable for use in the marine environment. This article will review the corrosion of reinforcing bars in concrete structures, the method of galvanizing steel bars, the various properties of galvanized steel bars, and their use methods. 1. Corrosion of steel bar in concrete Reinforced concrete structures in the marine environment, often
