最近,苏联的莫斯科定型设计和实验设计科学研究设计院与别斯古德尼柯夫建筑材料和结构综合厂协作,研制成一种新型的复合外墙板。这种墙板是以陶粒混凝土作为内、外层,聚苯乙烯为芯层的三层住宅用墙板,这是一项突破性的成就,在建筑业中取得了很好的经济效益。 Recently, the Soviet Union’s Moscow Institute of Design and Experimental Design Scientific Research and Design Collaborated with Bies Gudnikov’s Building Materials and Structures Complex to develop a new type of composite facade panel. This type of wallboard is a three-story residential wallboard with ceramsite concrete as the inner and outer layers and polystyrene as the core layer. This is a breakthrough achievement and has achieved very good economic benefits in the construction industry.
