据介绍俄罗斯已开发出粉煤灰陶粒新品种一免烧粉煤灰多孔轻骨料（俄称“灰渣孔料”），并在其试验基地建成一条半工业性生产线正在运作。产品主要性能列于下表，并与粘土陶粒进行比较：由表可见，此产品性能优于粘土陶粒：在同等堆积密度时，强度高30～40％，吸水率低20～40％ According to reports, Russia has developed a new type of fly ash ceramsite-free fired fly ash porous lightweight aggregate (Russian “ash slag hole material”), and built a semi-industrial production line in its test base is in operation. The main properties of the products are listed in the following table and compared with clay ceramsites: As can be seen from the table, this product has better performance than clay ceramsites: when the same bulk density, the strength is 30-40% higher and the water absorption is lower 20-40%.
