Portland cement clinker and preparation method thereof
The invention relates to the technical field of building materials, in particular to Portland cement clinker and a preparation method thereof.The method comprises the steps that 1, direct coal liquefaction residue raffinate, a calcium raw material and a siliceous raw material are mixed to obtain a mixed raw material, the mixed raw material is subjected to first grinding treatment, and a cement raw material is obtained; and (2) preheating, calcining and secondarily grinding the cement raw material to obtain the Portland cement clinker, wherein in the step (1), the weight ratio of the direct coal liquefaction residue raffinate to the calcium raw material to the siliceous raw material is (20-50): (60-70): (10-20). The preparation method of the Portland cement clinker provided by the invention can effectively solve the problem of environmental pollution caused by residue raffinate solid waste, and reduces the resource consumption of Portland cement raw materials.
本发明涉及建筑材料技术领域，具体涉及一种硅酸盐水泥熟料及其制备方法，所述方法包括：(1)将煤直接液化残渣萃余物、钙质原料、硅质原料混合后得到混合原料，将所述混合原料进行第一粉磨处理，得到水泥生料；(2)将所述水泥生料经预热、煅烧、第二粉磨处理，得到所述硅酸盐水泥熟料；其中，在步骤(1)中，所述煤直接液化残渣萃余物、钙质原料、硅质原料的重量比为20‑50：60‑70：10‑20。本发明提供的硅酸盐水泥熟料的制备方法可有效解决残渣萃余物固废对环境的污染，并减少硅酸盐水泥原料的资源消耗。
