目前,在胶东半岛流行一种复合加气混凝土砌块,该砌块是将含有加气剂的料浆,灌入小型混凝土空心砌块的空腔中复合制成。主要原材料为石渣或炉渣、粉煤灰、水泥和加气剂。产品性能除表观密度较高(900～950kg/m~3)外,其它各项性能均符合GB1196—89《加气混凝土砌块》3.5级品的要求。可 At present, a composite aerated concrete block is prevalent in the Jiaodong Peninsula. The block is made by compounding a slurry containing a gas-entraining agent into a cavity of a small-sized concrete hollow block. The main raw materials for the gravel or slag, fly ash, cement and air entraining agent. In addition to the product performance high apparent density (900 ~ 950kg / m ~ 3), the other properties are in line with GB1196-89 “aerated concrete block” 3.5 grade requirements. can
