Alkali-activated titanium slag extraction cement and preparation method thereof
The invention provides alkali-activated titanium slag extraction cement and a preparation method thereof. The alkali-activated titanium extraction slag cement is obtained by mixing the following raw materials in parts by mass: 2-20 parts of a solid alkali activator, 80-96 parts of titanium extraction slag, 0-30 parts of an auxiliary cementing material and 0-10 parts of an auxiliary agent, and 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, sodium hydroxide and solid sodium silicate; the auxiliary cementing material comprises an industrial solid waste material rich in amorphous silicon-aluminum oxide; the auxiliary agent comprises sodium carbonate and/or calcium sulfate. The method has the beneficial effects that the dependence on natural resources is reduced, the energy is saved, the energy consumption is low, the emission of CO2 is greatly reduced, and the environmental pollution is reduced.
本发明提供了一种碱激发提钛渣水泥以及制备方法。所述碱激发提钛渣水泥由按照质量份计的以下原料混合得到：2～20份固体碱激发剂、80～96份提钛渣、0～30份辅助胶凝材料和0～10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、氢氧化钠和固体硅酸钠中的一种或多种；辅助胶凝材料包括富含非晶态硅铝氧化物的工业固废材料；助剂包括碳酸钠和/或硫酸钙。本发明的有益效果可包括：降低了对自然资源的依赖，节约能源，低能耗，极大地减少CO2的排放，减轻环境污染。
