Road Portland cement and preparation method thereof
The invention relates to the technical field of cement preparation, and discloses road Portland cement and a preparation method thereof. The method comprises the following steps: (1) drying and grinding raw materials to obtain a raw material of which the sieve residue percentage of a 80-micron square hole sieve is 16-20%; (2) sequentially homogenizing, preheating, decomposing, calcining and cooling the raw material obtained in the step (1) to obtain clinker; and (3) mixing the clinker obtained in the step (2) with desulfurized gypsum, blast furnace water granulated slag and blast furnace steel slag, and then grinding. According to the method, limestone is replaced by solid waste generated in polyvinyl chloride production through a calcium carbide method. By optimizing a raw material and clinker proportioning scheme and clinker calcination process operation parameters, the road Portland cement clinker meeting national standard requirements can be produced, and carbide slag can be recycled.
本发明涉及水泥制备技术领域,公开了一种道路硅酸盐水泥及其制备方法。该方法包括以下步骤:(1)将原料进行烘干和粉磨处理,得到80微米方孔筛筛余百分比为16‑20%的生料;(2)将步骤(1)所得生料依次进行均化、预热、分解、煅烧和冷却,得到熟料;(3)将步骤(2)所得熟料与脱硫石膏、高炉水渣和高炉钢渣混合,然后进行粉磨。该方法利用电石法生产聚氯乙烯的固废替代石灰石,通过优化生料、熟料配料方案和熟料煅烧工艺运行参数,既能生产出符合国家标准要求的道路硅酸盐水泥熟料,还能对电石渣进行资源化利用。
