Desulfurized gypsum-based super sulfate cement and preparation method thereof
The invention provides desulfurized gypsum-based super sulfate cement and a preparation method thereof. The desulfurized gypsum-based super sulfate cement provided by the invention is prepared from the following components in percentage by mass: 10 to 40 percent of desulfurized gypsum, 1 to 10 percent of general cement, 30 to 60 percent of slag powder, 5 to 30 percent of steel slag, 5 to 30 percent of fly ash and 1 to 10 percent of composite exciting agent. The desulfurized gypsum, the steel slag, the blast furnace slag, the fly ash and other industrial solid wastes are matched with the cement clinker and the composite activator according to a certain proportion, the use amount of the desulfurized gypsum is 20% or above, a large amount of desulfurized gypsum and other industrial waste residues are utilized, the pollution of the industrial wastes to the environment is reduced, meanwhile, the early mechanical property of the material is remarkably improved, and the cost is reduced. And the strength gradient is formed by adjusting the ratio, so that the method can be applied to different engineering scenes.
本发明提供了一种脱硫石膏基超硫酸盐水泥及其制备方法。本发明提供的脱硫石膏基超硫酸盐水泥，包括以下质量比的组分：脱硫石膏10％～40％、通用水泥1％～10％、矿渣粉30％～60％、钢渣5％～30％、粉煤灰5％～30％、复合激发剂1％～10％。本发明采用脱硫石膏、钢渣、高炉矿渣、粉煤灰等工业固废与水泥熟料、复合激发剂以一定比例搭配，其中，脱硫石膏的用量在20％以上，大量利用了脱硫石膏及其他工业废渣、降低了工业废弃物对环境的污染，同时显著提升了材料的早期力学性能，还通过调整配比形成强度梯度使其可以应用于不同工程场景。
