Retarded alkali-activated titanium slag extraction cement and preparation method thereof
The invention provides retarded alkali-activated titanium slag extraction cement and a preparation method thereof. The retarded alkali-activated titanium slag extraction cement is prepared by mixing the following raw materials in parts by mass: 5-25 parts of a solid alkali activator, 80-100 parts of titanium slag extraction, 0-20 parts of an auxiliary cementing material and 1-10 parts of an auxiliary agent, wherein the titanium extraction slag is chlorine-containing titanium extraction tailings obtained by a high-temperature carbonization-low-temperature chlorination titanium extraction process; the solid alkali activator comprises one or more of quick lime, slaked lime and sodium carbonate; the auxiliary cementing material comprises one or more of phosphogypsum, granulated electric furnace phosphorus slag and calcium carbonate powder; the auxiliary agent comprises one or more of sodium lignin sulfonate, sodium sulfate and sodium phosphate. The method has the beneficial effects that the initial setting time and the final setting time are long, the construction time can be effectively prolonged, the cost is saved, the manufacturing cost is reduced, solid waste resource utilization is realized, waste is turned into wealth, and energy conservation and emission reduction are realized.
本发明提供了一种缓凝碱激发提钛渣水泥以及制备方法。所述缓凝碱激发提钛渣水泥由按照质量份计的以下原料混合得到：5～25份固体碱激发剂、80～100份提钛渣、0～20份辅助胶凝材料和1～10份助剂；其中，提钛渣为高温碳化‑低温氯化提钛工艺所得到的含氯提钛尾渣；固体碱激发剂包括生石灰、熟石灰、碳酸钠中的一种或多种；辅助胶凝材料包括磷石膏、粒化电炉磷渣、碳酸钙粉中的一种或多种；助剂包括木质素磺酸钠、硫酸钠、磷酸钠中的一种或多种。本发明的有益效果可包括：初凝和终凝时间长，可有效延长施工时间，节约成本，降低造价，并实现固废资源化利用，变废为宝，节能减排。
