Among which the experiment group using 50% fly ash, 10% silica fume instead of ordinary Portland cement shows rather better durability either in standard curing or the accelerated aging experiment. 其中以粉煤灰50%、硅灰10%取代普通硅酸盐水泥的试验组，无论是试验室标准养护或是加速老化试验都表现出最优的耐久性。 - 2
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. 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。 - 3
The comprehensive study on the impact and mechanism of mineral fillers, as fly-ash, Portland cement, slag-powder, hydrated lime and so on, improved asphalt concrete stability is scarce. 对于替代矿粉使用的粉煤灰、水泥、矿渣粉、石灰等填料对沥青混合料性能的改善效果及机理缺乏系统的研究。
