The invention relates to an all-solid waste cementing material, a novel roadbed material and a preparation method thereof, and relates to the field of building materials, the all-solid waste cementing material is prepared from, by mass, 10%-18% of desulfurized fly ash, 20%-40% of steel slag powder, 35%-55% of slag powder and 8%-12% of construction waste micro powder, and the desulfurized fly ash comprises calcium oxide, calcium sulfite and aluminum oxide; the novel roadbed material is prepared from the following raw materials in percentage by mass: 3%-6% of an all-solid waste cementing material, 5.5%-6% of water and 88%-91% of recycled aggregate, the preparation method comprises the following steps: metering the all-solid waste cementing material, adding metered recycled aggregate and water, and uniformly mixing. The problem of poor stability of the steel slag can be solved while strength support can be provided for a gelling system.
本申请涉及一种全固废胶凝材料、新型路基材料及其制备方法，涉及建筑材料领域，全固废胶凝材料以质量百分数计包括以下原料：10%‑18%的脱硫灰、20%‑40%的钢渣粉、35%‑55%的矿渣粉和8%‑12%的建筑垃圾微粉，脱硫灰包括氧化钙、亚硫酸钙和氧化铝；新型路基材料以质量百分数计包括以下原料：3%‑6%的全固废胶凝材料、5.5%‑6%的水和88%‑91%的再生骨料；制备方法包括计量全固废胶凝材料，再加入计量的再生骨料和水混合均匀。该申请能够为胶凝体系提供强度支持的同时解决钢渣安定性不良的问题。
