Superfine composite powder for cement and preparation method thereof
The invention discloses superfine composite powder for cement and a preparation method of the superfine composite powder, the superfine composite powder is composed of fly ash and mineral powder, and the superfine composite powder comprises silicon dioxide, aluminum oxide, ferric oxide, calcium oxide, magnesium oxide and sulfur trioxide. The inferior fly ash is reprocessed and utilized to ensure the mixing quality of the fly ash, hidden dangers caused by irregularity to stable cement quality are avoided, and meanwhile, the fly ash and the mineral powder are mixed and ground according to different proportions, so that the optimal effect is obtained, and the activity index, the water demand ratio and the fluidity of the cement are more obvious.
本发明公开了一种水泥用超细复合粉及其制备方法，所述超细复合粉由粉煤灰和矿粉组成，其中包含二氧化硅、三氧化二铝、三氧化二铁、氧化钙、氧化镁、三氧化硫。本发明通过将劣质的粉煤灰再加工利用保证粉煤灰的混合质量，避免参差不齐给水泥质量稳定造成隐患，同时通过将粉煤灰和矿粉按不同比例进行混合粉磨，进而得出最优效果，使水泥的活性指数、需水比、流动度更明显。
