摘要
根据我国有丰富的粉煤灰资源的现状,并以粉煤灰具有优异的成孔性能,可有效降低烧结砖的体积密度,提高其保温隔热性能为依据,为使粉煤灰砖具有高保温性能,必须同外燃砖一样具有高孔洞率的要求是否合理进行商榷。同时为促进粉煤灰的综合利用,本着科学、公平、公正和从一的原则,建议以“体积密度”和“导热系数”指标,取代国家标准《烧结多孔砖》中“孔洞率”的指标。
Good pore - producing property of fly ash can reduce volume density, improve thermal insulation of fired brick, which has high thermal insulation, The article discusses the rationality of high void ratio for fly ash fired brick, which is the same as external fuel -firing of brick.
