苏联拉脱维亚建筑科学研究所研制出了可用于两层楼建筑物的承重墙的石膏锯末混凝土砌块。由于砌块的尺寸精确,用石膏胶合料砌筑的墙体,墙面不用抹灰。石膏锯末混凝土的性能如下:在吸水率10%的情况下强度极限为2.5～3.5兆帕; The Soviet Latvian Institute of Building Research has developed a gypsum sawdust concrete block that can be used as a load-bearing wall in a two-story building. Due to the precise size of the blocks, the walls of the masonry walls are not plastered. The performance of gypsum sawdust concrete is as follows: In the case of 10% water absorption, the strength limit is 2.5 to 3.5 MPa;
