补充资料:轻骨料混凝土
分子式:
CAS号:

性质:又称为轻骨料混凝土(1ightaggregate concrete)。它是由胶凝材料和轻骨料配制而成的,容重不大于1900kg/m3。可分为全轻混凝土(用轻砂)与砂轻混凝土(用普通砂)。按用途可分为保温用的:密度为800kg/m3以下;结构保温用的:密度为800~1400kg/m3;结构用的:密度为1400kg/m3以上。轻骨料混凝土的耐热、防火性能较普通混凝土的好,但弹性模量则较低。以陶粒为粗骨料,以普通砂或陶砂为细骨料的轻骨料混凝土称为陶粒混凝土。结构用陶粒混凝土的强度可大于40MPa,保温及耐热性能较好。可用于房屋建筑、桥梁、船及窑炉基础等。
