苏联拉脱维亚的一个科研所研究成功一种聚合物混凝土。这种混凝土采用聚乙烯热塑性树脂作为胶结材科,采用诸如砂子、砾石、碎石、陶粒、珍珠岩等粒状材料作为骨料。利用这种混凝土作为畜舍的地板,具有良好的耐腐蚀性,无毒,物理力学性质也相当优越。这种混凝土地板可减少畜舍的热损耗,减少牲畜的发病率,提高畜产品的产量10—20％。采用这种混凝土地扳,畜舍可以少铺甚至不铺衬垫材料。这种混凝土的制造方法,是将指定粒级和比例的骨料加热,然后与聚乙烯搅拌均匀,在模子中成型,经振实冷却后,制成地板制品。
A scientific research institute in Latvia in the Soviet Union has successfully developed a polymer concrete. This type of concrete uses a polyethylene thermoplastic resin as a cementitious material and uses granular materials such as sand, gravel, gravel, ceramsite, and perlite as aggregates. The use of this concrete as a floor of a livestock house has good corrosion resistance, non-toxicity, and excellent physical and mechanical properties. This type of concrete floor can reduce the heat loss of livestock houses, reduce the incidence of livestock, and increase the output of livestock products by 10-20%. With this concrete pull, the barn can be made with little or no padding material. The method for manufacturing this concrete is to heat the specified aggregate and proportion of the aggregate, and then stir it evenly with polyethylene, form it in a mold, cool it after tapping, and make a floor product.
