| 摘 要： | 混凝土作为多孔结构的工程材料，在温度效应及外应力作用下，外界水分及有害物质可渗入到其毛细孔隙内部加速混凝土腐蚀，其耐久性受到影响。发展高性能混凝土防护涂料对于延长混凝土服役时间具有重要的作用。本文系统介绍了表面成膜型涂料、有机硅渗透型涂料、孔隙封闭型涂料对混凝土表层防护的研究现状、存在的问题以及发展方向。

| Abstract: | The concrete as a material of the porous engineering structures is easy to speed up the corrosion with outside water and harmful materials in temperature and external stress, and thus affecting the durability. Therefore, the high performance protective coatings of concrete have an important role in extending the service time. In this paper, the research status, existing problems and development direction of surface film-forming coating, silicone penetrating coating and pore closing coating on concrete surface protection were systematically introduced. |
