日本的钢筋混凝土住宅建筑物的法定耐用年限,一般为60年。对于结构受力主要部分和防水部分的缺陷,建筑开发商需承担10年的保修义务。建筑物为了防护风雨,不仅屋顶和外墙,而且阳台和敞廊等部位都要做防水。建筑物结构本身使用无机材料建造,但保护结构使用的防水材料多为有机材料,因此需要选择适当的材料进行维护管理。本文论述近年使用较多的涂膜防水和表面渗透型涂料应用中存在的问题和今后研究的方向。混凝土结构老化难以避免
The legal life span of residential buildings in Japan is generally 60 years. For the structural stress of the main part and the waterproof part of the defects, the developers need to assume 10 years warranty obligations. Buildings in order to protect the wind and rain, not only the roof and exterior walls, but also balcony and open air and other parts have to do waterproof. The structure of the building itself is made of inorganic materials, but most of the waterproofing materials used in the protective structure are organic materials, so the proper materials need to be selected for maintenance management. This article discusses the problems of applying water-repellent and surface-penetrating coatings in recent years and the future research directions. Concrete structure aging is difficult to avoid
