Novel carbon-sequestration low-calcium cementing material and preparation method thereof
The invention discloses a novel carbon-sequestration low-calcium cementing material and a preparation method thereof. The novel carbon-sequestration low-calcium cementing material is prepared from the following components in percentage by weight: 29.8 to 38.9 percent of beta-C2S, 12.7 to 28.3 percent of # imgabs0 #, 9.1 to 16.1 percent of Ca2Al2SiO7, 4.7 to 7.3 percent of Ca12Al14O3, 2.5 to 6.3 percent of Ca2MgSi2O7 and 13.7 to 23.9 percent of an amorphous phase. The cementing material is prepared by the following steps: completely taking municipal solid waste incineration waste residues (fly ash and bottom ash) as raw materials, uniformly mixing 61-80 parts of fly ash and 20-39 parts of bottom ash, tabletting to obtain a raw material cake, sintering at 1000-1200 DEG C at a heating rate of 5-10 DEG C/min, and cooling to obtain the carbon-sequestration low-calcium cementing material. The prepared novel cementing material has the excellent characteristics of low carbon fixation, early strength, high strength and the like, the cement production cost and calcination energy consumption are reduced, and meanwhile low-carbon production of the cement industry is fundamentally achieved through carbon reduction from the source, carbon reduction in the process and carbon removal at the tail end.
本发明公开一种新型固碳低钙胶凝材料及其制备方法，熟料矿物相占比为：β‑C2S:29.8～38.9％、#imgabs0#12.7～28.3％、Ca2Al2SiO7:9.1～16.1％、Ca12Al14O33:4.7～7.3％、Ca2MgSi2O7:2.5～6.3％和无定形相:13.7～23.9％。该胶凝材料完全以城市生活垃圾焚烧废渣(飞灰和底灰)为原料，将61～80份飞灰和20～39份底灰混合均匀，压片得到生料饼，后以5～10℃/min的升温速率在1000～1200℃内烧结、冷却，得到固碳低钙胶凝材料。本发明制备的新型胶凝材料，具有低碳固碳、早强高强等优异特性，不仅降低水泥生产成本和煅烧能耗，同时通过“源头减碳、过程降碳、末端除碳”，从根源上实现水泥工业的低碳生产。
