是以硅酸鹽水泥為基料，加入無機或有機外加劑配制而成的屋頂防水砂漿、屋頂防水混凝土，如外加氣屋頂防水混凝土，聚合物砂漿等；另—類是以膨脹水泥為主的特種水泥為基料配制的防小砂漿、屋頂防水混凝土，如膨脹水泥屋頂防水混凝土等。
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..
剛性屋頂防水材料按其作用又可分為有承重作用的屋頂防水材料(即結構自屋頂防水)和僅有屋頂防水作用的屋頂防水材料，前者指各種類型的屋頂防水混凝土，后者指各種類型的屋頂防水砂槳凝土結構自屋頂防水使用已久，在國外如原民主德國和日本較受正視。
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.
我國從50午代開始研究開發結構自屋頂防水技術百度快照優化，早期曾一度采用德國集料級配屋頂防水很凝土北京人事考試信息網，以后經過20多年的實踐和試驗研究，揭示了屋頂防水混凝土的屋頂防水原理，先后研制出適合我國國情的屋頂防水混凝土及外加劑屋頂防水混凝土遼寧人事考試網，在地下工程及各種屋頂防水、輸水、貯水工程中廣泛應用。
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.
近十幾年來，又采取各種措施，戰勝水泥、混凝土類材料抗拉強皮低、極限拉應變小肋瑕玷，削減總收縮值，增長混凝上的韌性，如采用聚合物混凝上，村沏凝土施加頸應力，在混凝土結構表而上附加各種屋頂防水層等方法，從而使剛性屋頂防水材料又有了新的發展。
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.
