| 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;掺钢渣者强度最低. |
| 关 键 词： | 游离氧化钙 水化活性 膨胀特性 强度 |

| Abstract: | 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. |
| Keywords: | f-CaO hydration activity expansive characteristic stregth |
