Manufacturing method of ultrafine powder cement admixture
The invention discloses a preparation method of an ultrafine powder cement admixture, which is prepared from the following raw materials in parts by weight: 30-50 parts of water granulated slag, 40-65 parts of fly ash and 5-10 parts of industrial desulfurization slag, the materials are mixed together according to the weight part ratio, the mixture is ground into powder with the specific surface area of 700-880m < 2 >/Kg, and the ultrafine powder cement admixture is prepared. The invention has the advantages that: 1, the mixed material of the water granulated slag, the fly ash and the industrial desulfurization slag is added into the cement instead of mineral powder, so that not only is the strength of the cement effectively improved, but also the production cost of the cement is reduced; 2, the water granulated slag, the fly ash and the industrial desulfurization slag are reasonably mixed, so that the activity of the cement product is effectively improved.
本发明公开了一种超细微粉水泥掺合料的制作方法，它由如下重量份的原料制作而成：水渣30‑50份、粉煤灰40‑65份和工业脱硫渣5‑10份，将上述材料依重量份配比混合在一起，磨制成比表面积为700‑880m2/Kg的粉状，本发明优点是：1、采用水渣、粉煤灰和工业脱硫渣的混配料代替矿粉添加到水泥中，不仅有效提高了水泥的强度，而且还降低了水泥的生产成本；2、通过采用水渣、粉煤灰和工业脱硫渣的合理混配，还有效提高了水泥产品的活性。
