１　引言我国１３０多家加气生产厂家在利用粉煤灰生产加气混凝土砌块产品的同时，每年产生几百万吨的加气碎块，堆积成山而无用途。有鉴于此，我们利用碎加气混凝土生产轻集料进而利用传统的加气生产线研制开发轻集料加气混凝土。２　原材料性能碎粉煤灰加气混凝土块由废品加 1 Introduction While more than 130 aerated manufacturers in China use fly ash to produce aerated concrete block products, they generate millions of tons of aerated pieces every year, which are piled up to form mountains without any use. In view of this, we use broken aerated concrete to produce light aggregates and then use traditional aerated production lines to develop light aggregate aerated concrete. 2 raw material performance crush fly ash aerated concrete block from waste plus
