苏联拉脱维亚建筑和工艺试验科研所用热塑性粘合剂(聚乙烯)和粒状填充料(砂、卵石、碎石、陶粒及珍珠岩)研制成用于修建畜舍地面的合成混凝土。这种混凝土具有高的化学稳定性、无毒,物理力学性能良好。合成混凝土能大大地减少热损失,可以 The Soviet Union’s Latvian Institute for Construction and Technology Experiments and Research Institute used thermoplastic binders (polyethylene) and granular fillers (sand, pebbles, gravel, ceramsite, and perlite) to develop composite concrete for the construction of barn grounds. This kind of concrete has high chemical stability, non-toxicity and good physical and mechanical properties. Synthetic concrete can greatly reduce heat loss and can
