烟灰陶粒是用烟灰摻入少部分粘土及木屑等物,在高溫下燒制的一种优质混凝土轻骨料袒姨樟]^之粘土陶粒,不但容重更轻、强度更高,而且成本低,制造简便,同时还可以节省許多粘土。烟灰陶粒配制的混凝土容重为1200～1600公斤/立方米,强度为100～250公斤/平方厘米。这种輕混凝土在建筑中可用做保溫层、承重楼板、装配式內外墙板等。1960年年底,北京市建筑工程公司曾试生产了一批烟灰陶粒,质量良好。現将其試驗和生产情
Ash ceramsite is a kind of high-quality concrete lightweight aggregate that is burned at high temperature with soot mixed with a small amount of clay and sawdust, etc. The clay ceramite not only has a lighter weight and a higher strength, but also Low cost, simple manufacturing, but also can save a lot of clay. The concrete density of the concrete made of soot ash is 1200 to 1600 kg/m3 and the strength is 100 to 250 kg/cm2. This kind of light concrete can be used as insulation layer, load-bearing floor, assembly type inner and outer wall plates in the building. At the end of 1960, Beijing Construction Engineering Company had tried to produce a batch of soot ash, which was of good quality. Now its test and production
