Method for preparing composite cementing material by doping biochar into red mud-ardealite-blast furnace slag and application of composite cementing material
The invention discloses a method for preparing a composite cementing material by doping biochar into red mud-ardealite-blast furnace slag and application of the composite cementing material. The method comprises the following steps: pre-soaking the biochar obtained by pyrolysis in water; the preparation method comprises the following steps: respectively drying, grinding and sieving red mud, phosphogypsum and blast furnace slag to obtain red mud particles, phosphogypsum particles and blast furnace slag powder; the biochar, the red mud particles, the ardealite particles, the blast furnace slag powder, the water and the activating agent are fully stirred, and the composite cementing material is obtained. The biochar, the red mud, the ardealite and the blast furnace slag can be converted into the composite cementing material with good durability and mechanical properties, and maximum consumption and resource utilization of bulk solid wastes of the red mud and the ardealite are realized. Compared with the prior art, the method is low in cost and simple to operate, can meet the road traffic requirements, realizes recycling, harmlessness and reduction of red mud and ardealite, achieves the goal of pollution reduction, carbon reduction and synergistic interaction, and generates better economic benefits, social benefits and environmental benefits.
本发明公开了一种生物炭掺入赤泥‑磷石膏‑高炉矿渣制备复合胶凝材料的方法及应用，将通过热解得到的生物炭，在水中进行预浸泡；将赤泥、磷石膏、高炉矿渣分别烘干研磨过筛，得到赤泥颗粒、磷石膏颗粒和高炉矿渣粉；将生物炭、赤泥颗粒、磷石膏颗粒、高炉矿渣粉、水和活化剂充分搅拌，得到复合胶凝材料。本发明能将生物炭、赤泥、磷石膏、高炉矿渣转化为具有良好耐久性和力学性能的复合胶凝材料，实现赤泥、磷石膏大宗固体废物的最大消纳和资源化利用。与现有技术相比，本发明成本低，操作简单，可满足道路交通要求，使赤泥、磷石膏资源化、无害化、减量化，达到减污降碳协同增效的目标，产生较好的经济效益、社会效益和环境效益。
