Carbon-sequestration all-solid waste cementing material prepared by wrapping biochar with hydrogel and preparation method of carbon-sequestration all-solid waste cementing material
The invention provides a carbon sequestration type all-solid waste cementing material prepared by wrapping biochar with hydrogel and a preparation method of the carbon sequestration type all-solid waste cementing material, and belongs to the technical field of carbon sequestration materials and solid waste resource utilization, and the preparation method comprises the following steps: preparing biochar-wrapped hydrogel, adding solid waste raw materials to obtain a gelatinizer sample, pre-curing, performing CO2 mineralization curing and the like. According to the invention, hydrogel is introduced to wrap biochar, multi-element solid wastes such as high-alkalinity industrial waste residues, high-activity industrial solid wastes, industrial byproduct lime putty and the like are utilized, and a CO2 mineralization maintenance technology is cooperated to prepare the carbon sequestration type all-solid waste cementing material. According to the method, the CO2 mineralization efficiency is effectively improved, the consumption of large-scale multi-element solid waste is realized, the dependence on traditional cement is reduced, and the carbon emission in the cement production process is reduced. Meanwhile, the raw material cost and resource consumption are reduced, and the double-carbon policy and solid waste resourceful treatment are promoted.
本发明提供了一种水凝胶包裹生物炭制备固碳型全固废胶凝材料及其制备方法，包括制备包裹生物炭的水凝胶、加入固废原料得到胶凝剂试样、预养护、CO2矿化养护等步骤，属于碳封存材料与固体废弃物资源化利用技术领域。本发明引入了水凝胶包裹生物炭，利用高碱性工业废渣、高活性工业固废、工业副产石灰膏等多元固废，并协同CO2矿化养护技术，制备固碳型全固废胶凝材料。该方法有效提高了CO2矿化效率，实现了大规模多元固废的消纳，减少了对传统水泥的依赖，降低了水泥生产过程中的碳排放。同时，降低了原料成本和资源消耗，推动了“双碳”政策和固废资源化处理的进行。
