Clinker-free cementing material containing high-content wet-discharged alkaline residues as well as preparation method and application of clinker-free cementing material
The invention discloses a clinker-free cementing material containing high-content wet-discharged alkaline residues as well as a preparation method and application of the clinker-free cementing material, and relates to the technical field of preparation of cementing materials from the wet-discharged alkaline residues. The clinker-free cementing material comprises a base material and a composite exciting agent, the base material comprises 40-60% of wet-discharged alkaline residues and 40-60% of slag in terms of dry-basis mass percentage, and the composite exciting agent comprises the base material and the slag in terms of dry-basis mass percentage, and the composite exciting agent comprises the base material and the slag in terms of dry-basis mass percentage, and the composite exciting agent comprises the base material and the slag in terms of dry-basis mass percentage. And the composite exciting agent is composed of NaOH and Na2CO3. The material disclosed by the invention can effectively replace cement, meanwhile, the treatment procedures of drying, grinding and the like are reduced, the energy consumption and the cost can be greatly reduced, the resource utilization of the alkaline residue solid waste is realized, and the 28d strength can reach more than 30MPa. According to the invention, a new cementing material is prepared from the wet-discharged alkaline residues, so that waste is turned into wealth, and the production cost is reduced while the environment is protected.
本发明公开了一种含大掺量湿排碱渣的无熟料胶凝材料及其制备方法和应用，涉及湿排碱渣制备胶凝材料技术领域。含大掺量湿排碱渣的无熟料胶凝材料，由基材和复合激发剂组成，其中，基材由湿排碱渣和矿渣组成，以干基质量百分比计湿排碱渣40~60%，矿渣40~60%；复合激发剂由NaOH和Na2CO3组成。本发明材料可有效替代水泥，同时减少烘干、磨细等处理工序，可大幅降低能耗和成本，实现碱渣固废的资源化利用28d强度可达30MPa以上。本发明使用湿排碱渣制备出一种新的胶凝材料，变废为宝，保护环境的同时降低了生产成本。
