Low-carbon cementing material and preparation method thereof
The invention relates to the technical field of building materials, in particular to a low-carbon cementing material and a preparation method thereof. The material mainly comprises the following raw materials in parts by mass: 25.0-40.0 parts of calcined coal gangue powder, 28.0-50.0 parts of Portland cement clinker, 20.0-30.0 parts of carbonized steel slag micro powder, 2.0-5.0 parts of gypsum, and a surfactant accounting for 0-0.1% of the total mass. The preparation method comprises the following steps: 1, weighing corresponding mass parts of Portland cement clinker, calcined coal gangue powder, carbonized steel slag micro powder, gypsum and a surfactant for later use; 2, grinding the Portland cement clinker in the step 1 into powder; 3, grinding the gypsum obtained in the step 1 into powder; and 4, uniformly mixing the carbonized steel slag micro powder, the calcined coal gangue powder, the Portland cement clinker powder, the gypsum powder and the surfactant to obtain the low-carbon cementing material, and providing an effective way for efficient utilization of a large amount of solid waste coal gangue and steel slag.
本发明涉及建筑材料技术领域，尤其是涉及一种低碳胶凝材料及其制备方法。该材料主要包括以下原料：25.0‑40.0质量份煅烧煤矸石粉，28.0‑50.0质量份硅酸盐水泥熟料，20.0‑30.0质量份碳化钢渣微粉，2.0‑5.0质量份石膏，外掺占总质量0‑0.1％的表面活性剂。该制备方法包括：1、称取相应质量份的硅酸盐水泥熟料、煅烧煤矸石粉、碳化钢渣微粉、石膏以及表面活性剂备用；2、将步骤一的硅酸盐水泥熟料磨成粉；3、将步骤一取得的石膏磨成粉；4、上述碳化钢渣微粉、煅烧煤矸石粉、硅酸盐水泥熟料粉、石膏粉及表面活性剂混合均匀，即得所述低碳胶凝材料，为大宗固废煤矸石和钢渣的高效利用提供一种有效途径。
