利用造纸黑液和粉煤灰-泥砂制备蒸压砖的研究

摘要

以粉煤灰、黄河泥砂为主要原料，炉渣为骨料，石灰、石膏为激发剂，用造纸黑液代替水做拌和液制备黄河泥砂-粉煤灰蒸压砖。结果表明，造纸黑液代水制备蒸压砖是可行的，制备的蒸压砖可以达到JC 239-2001《粉煤灰砖》规定的MU25级的质量要求。%Autoclaved brick is prepared by fly ash and Yellow River silt as main materials, waste papermaking liquor as mixing liquid. The results show that it is feasible to make autoclaved brick by waste papermaking liquor as mixing liquid. The autoclaved brick meets the demand of MU25 grade in JC 239-2001 (fly ash bricks) standard.
