在制作粉煤灰加气混凝土砌块过程中,因切割、发泡等原因,以及在施工中锯割、运输中会产生一些不规则的碎块,不能用于砌筑,但其保温性能并未降低,经过稍许加工后,完全可以用于屋面保温层,代替常用的水泥蛭石、水泥炉碴或整块加气混凝土等作法,它具有保温性能好、施工方便、造价低等优点。 In the process of producing fly ash aerated concrete block, due to cutting, foaming and other reasons, as well as sawing and transportation during construction, some irregular fragments will be produced and cannot be used for masonry, but their thermal insulation performance Without reduction, after a little processing, it can be completely used for roof insulation, instead of the commonly used cement vermiculite, cement furnace or aerated concrete, etc., it has the advantages of good insulation properties, convenient construction, and low cost.
