是以硅酸盐水泥为基料，加入无机或有机外加剂配制而成的屋顶防水砂浆、屋顶防水混凝土，如外加气屋顶防水混凝土，聚合物砂浆等；另—类是以膨胀水泥为主的特种水泥为基料配制的防小砂浆、屋顶防水混凝土，如膨胀水泥屋顶防水混凝土等。
Uses Portland cement as the base material, waterproof mortar, waterproof concrete adding inorganic or organic additive prepared, such as aerated waterproof concrete, polymer mortar; the other is based on the expansion of cement as special cement as the base material with anti small mortar, waterproof concrete, such as expansive cement waterproof concrete etc..
刚性屋顶防水材料按其作用又可分为有承重作用的屋顶防水材料(即结构自屋顶防水)和仅有屋顶防水作用的屋顶防水材料，前者指各种类型的屋顶防水混凝土，后者指各种类型的屋顶防水砂桨凝土结构自屋顶防水使用已久，在国外如原民主德国和日本较受正视。
Rigid waterproof materials according to their function can be divided into waterproof material bearing effect (i.e. self waterproof structure) and waterproof material waterproof effect only, the former refers to various types of waterproof concrete, the latter refers to various types of waterproof mortar concrete self waterproof structure has long been used in China, such as the former Democratic Germany and Japan more attention.
我国从50午代开始研究开发结构自屋顶防水技术百度快照优化，早期曾一度采用德国集料级配屋顶防水很凝土北京人事考试信息网，以后经过20多年的实践和试验研究，揭示了屋顶防水混凝土的屋顶防水原理，先后研制出适合我国国情的屋顶防水混凝土及外加剂屋顶防水混凝土辽宁人事考试网，在地下工程及各种屋顶防水、输水、贮水工程中广泛应用。
China's 50 generation from the afternoon began to research and development of structural self waterproofing technology was used in early German aggregate gradation is waterproof concrete, after 20 years of practice and experimental research, reveals the principle of waterproof waterproof concrete, has developed a waterproof concrete waterproof concrete admixtures and suitable for China's national conditions, widely used in the water storage project of underground engineering waterproof, water, and various.
近十几年来，又采取各种措施，战胜水泥、混凝土类材料抗拉强皮低、极限拉应变小肋瑕玷，削减总收缩值，增长混凝上的韧性，如采用聚合物混凝上，村沏凝土施加颈应力，在混凝土结构表而上附加各种屋顶防水层等方法，从而使刚性屋顶防水材料又有了新的发展。
In recent years, and take various measures to overcome the cement and concrete materials tensile strength of leather is low, the ultimate tensile strain of small rib defects, reduce the total shrinkage of concrete, increase the toughness, such as the use of polymer concrete, concrete applied a village neck stress in the concrete structure, and a variety of additional tables the waterproof layer and other methods, so that the rigid waterproof material and a new development.
