房建材料(包括墙体、屋面、保温、隔热、吸声、防水和装修材料等),它是建筑业的主要物质基础,是建材工业的重要组成部分。房建材料抓好了,对于建筑业以及整个基本建设工作都会发生重大影响,这对实现四个现代化,改善人民群众的居住条件,都会带来极大的好处。解放前房建材料主要是砖、瓦、灰、砂、石,私营小厂生产,技术十分落后。制砖是脚踩泥,手扣坯,自然晾晒,土窑焙烧。全国砖的产量只有十几亿块,仅供城市一般建筑使用。较高级的建筑则靠进口房建材科。广大农村建房多用土坯、石料、稻草、毛草、毛竹等,广大人民群众特别是农民的居住条件十分恶劣。 Housing construction materials (including walls, roofing, insulation, heat insulation, sound absorption, waterproofing, and decoration materials, etc.) are the main material basis of the construction industry and constitute an important part of the building materials industry. The construction of building materials will have a major impact on the construction industry and the entire capital construction work. This will bring great benefits to the realization of the four modernizations and improvement of the living conditions of the people. The building materials before the liberation were mainly bricks, tiles, ash, sand, and stone, and were produced by private small factories. The technology was very backward. The brick is a foot mud, a hand buckle blank, natural drying, roasting clay. The national output of bricks is only a few billion, and it is only used by ordinary buildings in cities. Higher-level buildings rely on Import House Building Materials Division. The vast majority of rural housing uses adobe, stone, straw, wool grass, bamboo, etc., and the living conditions of the broad masses of people, especially farmers, are very poor.
