Cement clinker, pavement cement and preparation method thereof
The invention provides a cement clinker, pavement cement and a preparation method thereof, and belongs to the technical field of concrete preparation. The cement clinker is prepared from the following raw materials in parts by weight: 84-86 parts of limestone; 6.8 to 7.2 parts of sandstone tailing powder; 4.7 to 4.9 parts of non-ferrous metal ash; 3.0 to 3.3 parts of aluminum tailing powder; the sandstone tailing powder contains more than or equal to 90% of SiO2 and less than or equal to 0.5% of R2O; the limestone contains more than or equal to 51% of CaO and less than or equal to 0.5% of R2O; the pavement cement comprises the following raw materials in parts by weight: 83.0-86.0 parts of the cement clinker; 3.8 to 4.2 parts of natural gypsum; 4.8 to 5.2 parts of sandstone tailing powder; 6.0 to 7.0 parts of stone powder; 0.03 to 0.05 part of a grinding aid; the pavement cement prepared by the invention has the effects of high breaking strength, good wear resistance, stable setting time and good adaptability to additives.
本发明提供了一种水泥熟料、道面水泥及其制备方法,属于混凝土制备技术领域,水泥熟料由如下重量份原料制得:石灰石84‑86份;砂岩尾矿粉末6.8‑7.2份;有色金属灰渣4.7‑4.9份;铝尾矿粉末3.0‑3.3份;所述砂岩尾矿粉末中SiO2≥90%,R2O≤0.5%;所述石灰石中CaO≥51%,R2O≤0.5%;道面水泥包括如下重量份原料:上述的水泥熟料83.0‑86.0份;天然石膏3.8‑4.2份;砂岩尾矿粉末4.8‑5.2份;石粉6.0‑7.0份;助磨剂0.03‑0.05份;本发明制得的道面水泥有抗折强度高、耐磨性好、凝结时间稳定、与外加剂适应性好的效果。
