Sulphoaluminate cement and preparation method thereof
The invention provides sulphoaluminate cement and a preparation method thereof. The preparation method comprises the following steps: sequentially adding deionized water and alkaline alcohol amine into the semi-dry desulfurization ash for pretreatment to obtain pretreated semi-dry desulfurization ash; gypsum, bauxite, limestone, the pretreated semi-dry desulfurization ash and a metal oxide additive are mixed to form a raw material, the raw material is homogenized and calcined, clinker is formed, and the sulphoaluminate cement is obtained. The invention also provides the sulphoaluminate cement prepared by the preparation method. The preparation method of the sulphoaluminate cement provided by the invention not only can realize resource utilization of the semi-dry desulfurization ash, but also can save lime consumption and promote CO2 emission reduction, and has great significance for environmental protection and economic development.
本发明提供了一种硫铝酸盐水泥及其制备方法。该制备方法包括：向半干法脱硫灰中依次加入去离子水和碱性醇胺进行预处理，得到预处理后的半干法脱硫灰；将石膏、铝矾石、石灰石、预处理后的半干法脱硫灰、金属氧化物添加剂混合形成生料，对生料均化、煅烧，形成熟料，得到所述硫铝酸盐水泥。本发明还提供了由上述制备方法得到的硫铝酸盐水泥。本发明提供的上述硫铝酸盐水泥制备方法不仅可以实现半干法脱硫灰的资源化利用，而且可以节约石灰消耗、促进CO2减排，对环保与经济发展具有重大的意义。
