Desulfurization ash-based soil curing agent and preparation method thereof
The invention discloses a desulfurization ash-based soil curing agent and a preparation method thereof. The desulfurization ash-based soil curing agent comprises the following components in parts by weight: 100-400 parts of Portland cement and 400-700 parts of mineral powder, or further comprises 1-300 parts of heavy steel desulfurized ash and/or 1-300 parts of E steel desulfurized fly ash. The desulfurization ash-based soil curing agent is used for road base reinforcement according to a mass doping amount of 4%-15%. The desulfurization ash-based soil curing agent meeting the performance requirements of DG/T J08-2082-2017 GS Soil Hardener Application Technical Regulations is prepared through formula adjustment, the production cost is reduced, and meanwhile, the resource utilization level of solid wastes such as sintered desulfurized ash is improved through large-scale utilization of the solid wastes such as the resintered desulfurized ash. Al2O3 and SiO2 in the desulfurization ash are sintered to react with Ca(OH)2 to generate C-S-H and ettringite, and strength is provided for the desulfurized fly ash-based curing agent stabilized soil.
本发明公开了一种脱硫灰基土体固化剂及其制备方法，按重量份计包括硅酸盐水泥100–400份和矿粉400–700份，或还包括重钢脱硫灰1–300份和/或鄂钢脱硫灰1–300份，该脱硫灰基土体固化剂按照质量掺量为4％–15％用于道路基层加固。本发明通过配方调整制备满足DG/T J08‑2082‑2017《GS土体硬化剂应用技术规程》性能要求的脱硫灰基土体固化剂，降低生产成本的同时通过大规模利用重烧结脱硫灰等固体废弃物，提高烧结脱硫灰等固废的资源化利用水平，通过烧结脱硫灰中Al2O3、SiO2与Ca(OH)2反应生成C‑S‑H与钙矾石，为脱硫灰基固化剂稳定土提供强度。
