现有的大模大板建筑体系尚存在自重大、水泥用量高及外墙板保温性能差等问题。建筑外墙保温不好,使墙板内表面结露,房间潮湿,家俱衣物发霉。因此外墙保温问题更成为人们普遍关心的问题,也是发展大模大板建筑体系的技术关键。无砂大孔陶粒混凝土(以下简称大孔混凝土)是不用砂,由陶粒和水泥浆粘结 The existing large-mold and large-scale building systems still have problems such as self-importantness, high cement consumption, and poor thermal insulation performance of exterior wall panels. The external wall of the building is not well insulated, which causes condensation on the inner surface of the wallboard. The room is damp and the furniture is moldy. Therefore, the problem of external wall insulation has become a common concern for people and a key to the development of large-scale and large-scale building systems. Sandless large hole ceramsite concrete (hereinafter referred to as macroporous concrete) is sand-free and is bound by ceramic particles and cement paste.
