Red mud-based carbon sequestration cementing material with low carbon emission as well as preparation method and application of red mud-based carbon sequestration cementing material
The invention relates to a low-carbon-emission red mud-based carbon sequestration cementing material and a preparation method and application thereof, and the cementing material comprises 32-80 parts of red mud, 8-20 parts of cement and 20-60 parts of gamma-C2S. A preparation process of the gamma-C2S comprises the following steps: mixing a calcium raw material and a siliceous raw material according to a calcium-silicon molar ratio of 2: 1 by ball milling to obtain a sintered raw material, mixing the sintered raw material with absolute ethyl alcohol with a mass fraction of 10%, pressing into a green body, drying, putting the raw material into a muffle furnace, and calcining at a heating rate of 10 DEG C/min and a calcining temperature of 1350 DEG C to prepare the gamma-C2S. The heat preservation time is 3 h, and the gamma-C2S clinker is obtained. The invention also provides a preparation method of the low-carbon low-emission solid waste-based cementing material. According to the technical scheme, the problems that in the prior art, the preparation process of the cementing material is complex in technology and large in carbon emission are solved.
本发明涉及一种低碳排的赤泥基固碳胶凝材料及其制备方法和应用，该胶凝材料，包括赤泥32‑80份、水泥8‑20份、γ‑C2S 20‑60份。所述γ‑C2S的制备工艺如下：按照2:1的钙硅摩尔比，将钙质原料与硅质原料混球磨混合，得到烧成原料，将所述烧成原料与质量分数为10％的无水乙醇混合，压制成坯体，烘干后，再将生料放入马弗炉中煅烧制备，升温速率为10℃/min，煅烧温度为1350℃，保温时间为3h，得到γ‑C2S熟料。本发明还提出了一种低碳低排固废基胶凝材料的制备方法。通过上述技术方案，解决了现有技术中的胶凝材料的制备过程工艺复杂，碳排放量较大问题。
