摘　　要：研究了矿渣、粉煤灰和烧页岩单掺及复掺对高阿利特水泥凝结时间、抗压强度、电阻率、水化产物组成及微观结构的影响.结果表明:掺加大量混合材后,高阿利特水泥仍具有较高的强度;电阻率发展能反映出混合材的掺加将减缓高阿利特水泥早期水化的发展;适当掺加混合材可优化水化产物组成,提高水化产物结构致密性.The effect of slag,fly ash,and calcined shale on setting time,compressive strength,resistivity,composition and microstructure of hydrated product of alite-rich Portland cement were studied.Results show that with vast amount of blending material added,alite-rich cement can still provide higher strength.The development of resistivity is related to early hydration,and slowed by blending materials.Proper adding of blending materials can optimize the composition of hydrated product and the microstructure.
