Alkali-activated cementing material based on multi-element industrial waste residues and preparation method of alkali-activated cementing material
The invention belongs to the technical field of solid waste resource utilization, and relates to an alkali-activated cementing material based on multi-element industrial waste residues and a preparation method of the alkali-activated cementing material. Industrial waste residues such as slag, fly ash, steel slag, silica fume, carbide slag and gypsum are used as raw materials and matched with an alkali-activated solution, and the alkali-activated cementing material is prepared. The alkali-activated cementing material provided by the invention has the advantages of low preparation cost, high strength, good durability, low shrinkage, low permeability and the like, can be used as a substitute material of traditional Portland cement, reduces carbon emission in a cement manufacturing process, has a wide application prospect in the fields of buildings, roads, bridges, tunnels and the like, and is worthy of popularization and application. Meanwhile, a reference way is provided for research of novel building materials. According to the invention, various industrial waste residues are subjected to resource utilization, and land occupation or environmental pollution caused by improper treatment of the industrial waste residues can be relieved.
本发明属于固体废弃物资源化利用技术领域，涉及一种基于多元工业废渣的碱激发胶凝材料及其制备方法。本发明利用矿渣、粉煤灰、钢渣、硅灰、电石渣、石膏等工业废渣为原料，配合碱激发溶液，制备得到一种碱激发胶凝材料。本发明提供的碱激发胶凝材料，具有制备成本低、强度高、耐久性好、收缩低、渗透性低等优点，可作为传统硅酸盐水泥的替代材料，减少水泥制造过程中的碳排放，在建筑、道路、桥梁、隧道等领域有着广阔的应用前景，同时为新型建筑材料的研究提供参考途径。本发明将多种工业废渣加以资源化利用，还能帮助缓解工业废渣的不当处理造成的土地占用或环境污染。
