摘要
主要研究了不同粉磨时间的粉煤灰密度、比表面积、粒度分布等颗粒特性的变化规律,以及研究了将不同粉磨时间的粉煤灰按30%比例掺人硅酸盐水泥中的水泥性能变化情况。结果表明:随着粉磨时间的增加,粉煤灰颗粒的密度、比表面积和粒度分布都呈有规律的变化;其中粉磨60 min时的粉煤灰水泥性能达到最佳。
The change rule of fly ash" particle characteristics of density, specific surface area and particle size distribution in different grinding time was studied as well as the performance change rule of Portland cement added 30% fly ash at different grinding time. The results show that with the increasing grinding time, the density, surface area and particle size distribution of fly ash changed regularly and the properties of cement with fly ash at 60 min grinding time was the best.
