一、概况页岩陶粒是将页岩经破碎、筛分后,在回转窑内经高温快速烧胀而成的人造轻骨料,见图1。用它可以配制适应各种用途的页岩陶粒混凝土,具有容量轻、隔热性能好、能防火等优点。与普通混凝土相比,重量轻25～50%,做结构材料,可降低重量25%以上。它是实现建筑业“三化”和墙体技术改革的重要材料之一。 I. Overview Shale ceramsite is a man-made lightweight aggregate obtained by crushing and screening shale and then rapidly swelling at high temperature in a rotary kiln. It can be used to prepare shale ceramsite concrete that can be used for various purposes. It has the advantages of light weight, good thermal insulation performance, and fire resistance. Compared with ordinary concrete, the weight is 25 to 50% lighter. As a structural material, the weight can be reduced by more than 25%. It is one of the important materials for realizing the “threeizations” of the construction industry and the reform of the wall technology.
