摘要
以粉煤灰加气混凝土砌块为研究对象,探讨磷石膏掺量变化对加气混凝土砌块性能的影响。实验表明,石灰掺量质量分数20%,磷石膏在粉煤灰加气混凝土砌块中掺量增加,强度提高。最佳掺量3%,强度、表观密度和导热系数性能最佳。
With fly ash aerated concrete block as the research object,explore phosphorus gypsum content change effect on the properties of aerated concrete block.Experimental results show that lime content is 20 % mass fraction,phosphogypsum in the increase of the admixture of coal fly ash aerated concrete block in intensity increased.Optimal dosage of 3 %,intensity,apparent density and thermal conductivity performance best.
