Low-carbon high-strength cementing material prepared from coal gangue power plant solid waste and preparation method
The invention relates to the technical field of building materials, in particular to a low-carbon high-strength cementing material prepared from coal gangue power plant solid waste and a preparation method. The material comprises the following components by mass: 30-50 parts of Portland cement clinker, 25-50 parts of coal gangue power plant ash, 5-15 parts of furnace bottom slag, 5-12.5 parts of limestone, 2.5-5 parts of gypsum and a modifier accounting for 0.5wt% of the furnace bottom slag. The preparation method comprises the following steps: 1) taking materials according to the raw material mass ratio; 2) grinding the Portland cement clinker obtained in the step 1), limestone and gypsum together to a specific surface area of 300-400m<2>/kg; 3) uniformly mixing the furnace bottom slag obtained in the step 1) with the modifier, and performing grinding to a specific surface area of 350-550m<2>/kg; and 4) uniformly mixing the coal gangue power plant ash obtained in the step 1) with the finely ground powder obtained in the step 2) and the step 3) to obtain the low-carbon high-strength cementing material.
本发明涉及建筑材料技术领域，尤其是涉及一种利用煤矸石电厂固废制备的低碳高强胶凝材料及制备方法。该材料包括：30‑50质量份硅酸盐水泥熟料，25‑50质量份煤矸石电厂灰，5‑15质量份炉底渣，5‑12.5质量份石灰石，2.5‑5质量份石膏和在炉底渣中占比0.5wt％的改性剂。制备方法包括：1)按照原料质量比例取料；2)将步骤1)取得的硅酸盐水泥熟料、石灰石和石膏，共同粉磨至比表面积300‑400m2/kg；3)将步骤1)取得的炉底渣和改性剂混匀，粉磨至比表面积350‑550m2/kg；4)将步骤1)取得的煤矸石电厂灰和步骤2)与步骤3)所得磨细粉体混合均匀，即得低碳高强胶凝材料。
