Production process of retarded Portland cement for road base
The invention provides a production process of retarded Portland cement for a road base, which belongs to the technical field of cement production, and comprises the following steps: grinding limestone, clay, iron ore and coal into powder to prepare a cement raw material; firing the cement raw material to prepare cement clinker, carrying out heat preservation on the cement clinker, mixing the cement clinker, gypsum, fly ash and mineral powder, and grinding into clinker powder; arranging a plurality of parts of clinker powder and a plurality of parts of white sugar to form clinker powder layers and white sugar layers, wherein each part of white sugar is uniformly scattered on the clinker powder layer below, so that each white sugar layer is in a molten state and is adhered to the clinker powder layer; and finally, grinding and homogenizing to form the cement product. According to the production process of the retarded Portland cement for the roadbase, the clinker powder layer and the white sugar layer are arranged layer by layer, and the white sugar is heated to a molten state by the high-temperature clinker powder layer, so that the white sugar and the clinker powder are uniformly mixed and firmly combined, the accuracy of preparing the retarded Portland cement is improved, and the retarded effect is relatively good.
本发明提供了一种道路基层用缓凝硅酸盐水泥生产工艺,属于水泥生产技术领域,包括将石灰石、黏土、铁矿石及煤研磨成粉而制备为水泥生料;对水泥生料进行烧制加工而制备为水泥熟料,将水泥熟料进行保温,将水泥熟料、石膏、粉煤灰和矿粉混合并研磨成熟料粉;将多份熟料粉、多份白糖布置形成熟料粉层和白糖层,各份白糖均匀撒在下方的熟料粉层上使各白糖层呈熔融态而粘结附着于熟料粉层上;最后研磨并均化形成水泥制品。本发明提供的道路基层用缓凝硅酸盐水泥生产工艺,逐层布置熟料粉层和白糖层,由高温的熟料粉层对白糖进行加热至熔融态,使白糖与熟料粉混合均匀且结合牢靠,从而提高了制备缓凝水泥的准确性,且缓凝效果较好。
