摘要
本文研究了粉煤灰细度、颗粒形貌及掺量对水泥和混凝土强度及混凝土流变性能的影响。研究结果证明，掺入二、三电场的原状粉煤灰对混凝土强度影响不大，但可以较为显著地改善新拌混凝土的流变性能，而掺入磨细粉煤灰既可以改善水泥和混凝土的力学性能，又可以改善混凝土的流变性能。
The effects of fineness, particle appearance and adding amounts on the strengths of cement and concrete as well as the concrete rheological behavior are studied in this paper. Test results show that when raw fly ash from No2 and No. 3 power plants is added the concrete strength is hardly affected, but the rheological behavior of the freshly - mixed concrete can be remarkably improved. the addition of ground fly ash can significantly improve both the mechanical properties of cement and concrete and the rheological behavior of concrete
