摘要
研究了粉煤灰细度、颗粒形貌及掺量对水泥强度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的强度影响不大，但可以较为显著地改善新拌混凝土的流变性能，而掺入磨细的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，因此。
The effects of fineness and particle appearance of fly ash on the properties of cement and its concrete are studied.The test results show that the fineness of fly ash does not affect the mechanical properties of cement and its concrete,but affect the rhyology of concrete significantly.The ground fly ash can significantly improve both mechanical and rhyological properties of concrete.
