苏联拉托维亚建筑科学研究院最近研制出了一种农房用承重石膏木屑墙块。该墙块在干燥和正常情况下可用作两层楼房的承重墙。由于该墙块具有精确的尺寸,采用胶质石膏灰浆砌筑,因而砌成的墙体表面不需再次抹灰。该墙块采用石膏木屑混凝土制备。其混凝土物理力学性能:含水率10％的条件下,极限 The Soviet Latvia Institute of Building Sciences has recently developed a load-bearing gypsum wood chip block for rural housing. The wall block can be used as a load-bearing wall for a two-story building under dry and normal conditions. Since the wall block has a precise size, it is plastered with colloidal gypsum plaster, so that the wall surface of the built-up wall does not need to be plastered again. The wall block is made of gypsum woodchip concrete. The concrete physical and mechanical properties: the limit of water content 10%, the limit
