摘　　要：处于严酷环境下的钢筋混凝土易受到环境介质如氯离子的侵蚀破坏,影响结构的使用寿命,严重的甚至影响结构的安全运行。混凝土表面涂覆防护涂料(封闭型和渗透型)是钢筋混凝土防护措施之一,目前已在许多工程上得到应用。本文主要介绍了国内交通、铁路和水利等行业中混凝土表面涂料的应用情况,重点介绍涂料和有机硅渗透型防护剂的应用情况,包括行业规范中的规定和要求等,并对未来混凝土表面防护涂料的研究开发和应用提出建议。The reinforced concrete served in harsh environment is easy to be attacked by environmental media such as chlorine ion, reducing the service life of the structures and even affecting the safety operation of the structures. Using protective coatings (barrier or permeable) on concrete surface is one of the protective measures for reinforced concrete, which has been applied in many projects. This paper mainly introduced the application of concrete surface coatings in transportation, railway and water conservancy industries in China, especially the application of organic coatings and silicone impregnating agents, including the specifications and requirements in domestic regulations. Finally, some suggestions on the research, development and application of concrete surface protective coatings in the future were proposed.
