摘要
本文选取四种不同减水特性的粉煤灰，研究其随掺配方法及取代量的不同在砂浆中的减水规律特性，试验结果表明：粉煤灰减水特性指标是表征其品质的主要指标；体积取代法比质量取代法更能发挥粉煤灰的减水特性。
In this paper, 4 kinds of fly ash with different water-reducing properties are selected and their regular water-reducing properties with different mixing methods and replacement quantities of fly ash in mortars are studied. Test results show that the index or water-reducing property of fly ash is the main index indicating the quality and that the volume replacement method can better develop the water-reducing property of fly ash than the mass replacement method.
