Improvement method of high-performance green cement producd by double doping grinding aid and mineralized material
The invention discloses an improvement method of high-performance green cement produced by double doping a grinding aid and a mineralized material. The method comprises the following steps: S1, raw material preparation: preparing sufficient clinker, mineralized material, limestone, superfine slag powder, desulfurized gypsum and the grinding aid; S2, reference group test: cement components comprise the following components in weight: preparing 4,500 grams of clinker, 175 grams of limestone, 500 grams of superfine slag powder and 325 grams of desulfurized gypsum, and acquiring data of grinding time, water consumption, initial setting, final setting, fineness, specific surface, sulfur trioxide, ignition loss, neat paste fluidity, fracture resistance, compression resistance and hexavalent chromium, the data number being A1. The method has the beneficial effects that the calibration blank of the clinker is reduced, the strength is improved, the standard consistency water consumption is reduced, the ratio of hexavalent chromium to high value is reduced, the content of hexavalent chromium in the cement can be effectively eliminated, and a chromium remover does not need to be purchased independently.
本发明公开了一种双掺助磨剂和矿化料生产高性能绿色水泥的提高方法，包括以下步骤：S1、原料准备，准备足量的熟料、矿化料、石灰石、矿渣微粉、脱硫石膏和助磨剂；S2、参照组试验，水泥成分重量分别为：熟料准备四千五百克，石灰石准备一百七十五克，矿渣微粉准备五百克，脱硫石膏准备三百二十五克，对粉磨时间、用水量、初凝、终凝、细度、比表、三氧化硫、烧失量、净浆流动度、抗折、抗压和六价铬数据进行采集，数据编号为A1。本发明有益效果是：熟料对标空白下降，提高了强度，标准稠度用水量下降，六价铬同高值比下降，可以有效消除六价铬在水泥中的含量，可不必单独购买除铬剂。
