摘要
利用磷渣的潜在活性,研制了以磷渣为原材料的加气混凝土。研究了标准养护和蒸压养护两种养护方式对磷渣加气混凝土体积密度、抗压强度、干燥收缩、抗冻性和导热系数等性能的影响。结果表明,与标准养护相比,蒸压养护可以降低磷渣加气混凝土的体积密度、干燥收缩值和导热系数,提高加气混凝土的抗冻性能。
Aerated concrete was prepared by phosphorus slag with its activity. The influence of standard and autoclaved curing to bulk density, compressive strength, dry shrinkage, frost resistance and thermal conductivity were studied. The results indicate that autoclaved curing can reduce the bulk density, dry shrinkage and thermal conductivi- ty of the aerated concrete with phosphorus slag and improve the frost-resistance to standard curing.
