摘要
研究了改性高钙粉煤灰按不同比例掺入硅酸盐水泥后其净浆和砂浆的基本物理力学性能，并与未经改性的原状高钙粉煤灰做比较。结果表明，改性高钙粉煤灰在较高掺比情况下的性能与未经改性的原状高钙粉煤灰不同，体积安定性合格，强度有所提高，净浆需水量增加，而砂浆流动性差别不大。
The study deal with the effects of two high calcium fly ashes, ordinary and modified, on water demand, setting time, soundness of cement paste and compression and flexural strength of mortar. The results indicate that the volume soundness of pastes with 10～70% replacement of cement by modified high calcium fly ash is satisfactory in compare with the original high calcium fly sah.
