一种新型墙体材料——粉煤灰珍珠岩轻质空心砌块最近在内蒙古通辽市正式投入生产。这种新产品是由通辽保温建材实业公司经过四年半时间研制成功的。它以粉煤灰为原料,膨胀珍珠岩为骨料,水泥为胶结材料,并配以适量外加剂,经高频振捣成型机制成。该产品具有容重轻,导热系数小,吸音性能好,可锯和可钻孔等优点,是工业民用建筑中非承重的理想墙体材料和保温节能材料。该 A new type of wall material - fly ash perlite lightweight hollow block recently formally put into production in Tongliao City, Inner Mongolia. This new product by Tongliao insulation building materials Industry Company after four and a half years of successful development. It uses fly ash as raw material, expanded perlite as aggregate, cement as cementing material, and with proper admixture, made by high-frequency vibrating molding machine. The product has the advantages of light weight, small thermal conductivity, good sound-absorbing performance, sawing and drilling, etc. It is the ideal non-load-bearing wall material and thermal insulation energy-saving material in industrial civil buildings.
