本文以循环流化床锅炉（C FBB ）灰渣为主要原料，通过实验获得了其制备免烧砖的最佳工艺配料为：石灰7％、飞灰43％、底渣30％、骨料瓜子石20％。通过蒸汽养护和自然养护对比，发现在低石灰掺量时，自然养护效果明显低于蒸汽养护，但随着石灰用量的增加，二者差异逐渐缩小，当高于7％时，检测结果基本一致，在此基础上，通过扩大性工业试验，采用自然养护方式，可生产标号为150的免烧砖砌块。

In this paper ,circulating fluidized bed boiler (CFBB) ash is used as the main raw material for preparing baking free brick to obtain through experiment the optimal ingredients as follows :7% lime ,43%fly ash ,30% bottom ash ,20% aggregate of oval stone .By steam curing and natural curing contrast ,we find that the effect of nature curing is significantly lower than the steam curing .But with the increasing of lime dosage ,the difference is gradually reduced .When lime dosage is higher than 7% ,the test results are basically consistent .On this basis ,unburned block labeled 150 can be produced using natural curing method through the expansion of industrial test .
