摘要
不同物料中f-CaO的水化活性、膨胀特性及其对硬化水泥浆体强度的影响各不相同。高钙粉煤灰中的f-CaO水化最快 ,试样膨胀主要发生在 7天以内 ;水泥熟料中的次之 ;钢渣中的水化最慢 ,试样膨胀稳定期超过 56天。掺高f-CaO熟料的试样强度最高 ;掺高钙粉煤灰者次之 ;
To different materials, hydration activity of f-CaO, expansive characteristic and influence of harden cement pastes's strength are not the same. Hydration speed of high-Ca fly ash is the fastest, it's expansion occurred in 7 days. The later is cement clinker. The last is steel slag, it's expansive stability period exceeds 56 days. High f-CaO samples have the highest strength, the later is high-Ca fly ash samples, the last is steel slag samples.
