Highway engineering cement prepared based on lead smelting slag
The invention relates to the technical field of solid waste resource utilization and building materials, in particular to highway engineering cement prepared based on lead smelting slag. The highway engineering cement prepared based on the lead smelting slag is prepared from the following raw materials in parts by mass: 15 to 35 parts of lead smelting slag, 19 to 44 parts of slag, 25 to 40 parts of cement clinker and 4 to 6 parts of gypsum. The lead smelting slag and the slag are subjected to resource utilization, the hydration activity of the metallurgical slag is improved through the synergistic excitation effect of the Portland cement clinker and the gypsum, and the mechanical strength requirements of cement for heavy, medium and light load grade road surface layers can be met; meanwhile, the 28d dry shrinkage rate and the setting time of the highway engineering cement both meet the industrial index requirements. Finally, the utilization rate of the lead smelting slag and the slag is high, the clinker mixing amount is small, the resource utilization level of industrial solid waste is improved, the production cost of the road cement is reduced, and good environmental protection and economic benefits are achieved.
本发明涉及固体废弃物资源化利用以及建筑材料技术领域，特别是涉及一种基于铅冶炼渣制备的公路工程水泥。按质量份数计，基于铅冶炼渣制备的公路工程水泥的原料包括：铅冶炼渣15～35份，矿渣19～44份，水泥熟料25～40份和石膏4～6份。本发明对铅冶炼渣和矿渣进行资源化利用，通过硅酸盐水泥熟料和石膏的协同激发作用，提高了冶金废渣的水化活性，可满足重、中、轻载荷等级公路面层用水泥的力学强度需要；同时，该公路工程水泥的28d干缩率、凝结时间均符合行业指标要求。最后，本发明中铅冶炼渣和矿渣的利用率高，熟料掺量小，既提高了工业固废的资源化利用水平，又降低了公路水泥的生产成本，具有良好的环保和经济效益。
