摘　　要：本文从低水胶比时 ,在水泥基中单掺不同量的超细粉煤灰和硅灰以及复合超细粉煤灰和硅灰对水泥与减水剂相容性影响的现象出发 ,阐述了低水胶比时矿物掺合料对水泥与减水剂相容性的影响及作用机理。Starting with how the cement simply mixed with different amount of ultra-fine f ly ash,silicon ash and the compound of ultra-fine fly ash and silicon ash will affect the compatibility of the cement and the superplasticizer,this paper anal yzes the influential mechanism of mineral admixture on the compatibility of the cement and the superplasticizer at low water binder ratio.

关 键 词：相容性 粉煤灰 硅灰 高效减水剂
