一、根据功能需求生产建筑材料。这些功能需求包括高强、保温,隔热、隔音等。例如,在混凝土和塑料方面,按照功能需求生产的建筑材料就有轻混凝土、高强混凝土、纤维混凝土以及复合材料等。二、用多种材料组合生产高性能建筑制品。用两种或两种以上材料组合生产高性能的复合产品。这种产品有石膏板、石棉-水泥制品、低辐射玻璃、双层隔热隔音玻璃、木组合梁和桁架,多层饰面材料,以及多层织成地毯等。三、塑料建材的应用日益广泛。四、合理利用低造价地方建筑材料。五、高度重视基础设施的建设。世界上许多国 First, produce building materials according to functional requirements. These functional requirements include high strength, thermal insulation, thermal insulation, and sound insulation. For example, in terms of concrete and plastic, building materials produced according to functional requirements include light concrete, high-strength concrete, fiber reinforced concrete, and composite materials. Second, use a variety of materials to produce high-performance building products. Combine two or more materials to produce high-performance composite products. Such products include gypsum board, asbestos-cement products, low-emissivity glass, double-layered heat-insulating glass, wood composite beams and trusses, multi-layered decorative materials, and multilayer woven carpets. Third, the application of plastic building materials is increasingly widespread. Fourth, rational use of low cost local building materials. Fifth, attach great importance to the construction of infrastructure. Many countries in the world
