Hemihydrate phosphogypsum-based water-resistant cementing material and preparation method thereof
The invention provides a hemihydrate phosphogypsum-based water-resistant cementing material and a preparation method thereof. The cementing material is prepared from, by mass, 60-95% of hemihydrate phosphogypsum, 0-15% of phosphorus slag powder, 1-30% of superfine slag powder, 0-10% of fly ash, 0-10% of Portland cement and 0-10% of quick lime; the contents of the Portland cement and the quick limeare not zero at the same time; and the crystal water content of the hemihydrate phosphogypsum is 4-12%. The hemihydrate phosphogypsum-based cementing material has relatively high strength and softening coefficient under the combined action of the components with the contents.
本发明提供了一种半水磷石膏基耐水型胶凝材料及其制备方法，胶凝材料以质量分数计，包括以下组分：半水磷石膏60～95％，磷渣粉0～15％，矿渣微粉1～30％，粉煤灰0～10％，硅酸盐水泥0～10％和生石灰0～10％；所述硅酸盐水泥和生石灰的含量不同时为0；半水磷石膏的结晶水含量为4～12％。该半水磷石膏基胶凝材料在上述含量的组分的共同作用下具有较高的强度和软化系数。
