Carbonized calcined coal gangue solid waste-based cementing material and preparation method thereof
The invention provides a carbonized calcined coal gangue solid waste-based cementing material and a preparation method thereof, and belongs to the technical field of coal gangue solid waste utilization. The carbonized coal gangue-based cementing material is prepared from the following raw materials: 30 to 70 parts of calcined coal gangue micro powder, 20 to 50 parts of premixed concrete waste residue, 10 to 20 parts of cement, 0 to 5 parts of gypsum, 0.5 to 1.0 part of surfactant and 0.1 to 0.5 part of organic amine. The preparation method comprises the following steps: firstly, crushing, grinding and calcining coal gangue solid waste; mixing the mixture with premixed concrete waste residues, ordinary Portland cement, gypsum, a surfactant and organic amine, introducing industrial carbon dioxide, and drying to obtain the cement. The performance index of the carbonized and calcined coal gangue solid waste based cementing material is equivalent to that of PO 42.5-grade cement, large-dosage utilization of the coal gangue solid waste and preparation of the low-carbon cementing material are achieved, the process is simple, and the practical application and popularization value is achieved.
本发明提出了一种碳化煅烧煤矸石固废基胶凝材料及其制备方法，属于煤矸石固废利用技术领域。本发明的碳化煤矸石基胶凝材料原料包括煅烧煤矸石微粉30‑70份、预拌混凝土废渣20‑50份、水泥10‑20份、石膏0‑5份、表面活性剂0.5‑1.0份和有机胺0.1‑0.5份，首先对煤矸石固废进行破碎、磨粉和煅烧处理，后将其与预拌混凝土废渣、普通硅酸盐水泥、石膏、表面活性剂和有机胺进行混合，然后通入工业二氧化碳并进行干燥处理得到。本发明中碳化煅烧煤矸石固废基胶凝材料的性能指标与PO 42.5级水泥相当，实现了煤矸石固废大掺量利用和低碳胶凝材料的制备，工艺简单，具有实际推广应用价值。
