Steel slag modified cementing material as well as preparation method and application thereof
The invention belongs to the technical field of solid waste resource utilization, and discloses a steel slag modified cementing material, a preparation method and application, and the preparation method comprises the following steps: S1, collecting high-temperature steel slag; s2, regulating and controlling components of the molten steel slag under heat preservation; s3, phase modification and reconstruction in the heat preservation stage; s4, reconstructing a first-stage cooling phase of the modified steel slag; s5, carrying out second-stage cooling phase reconstruction on the modified steel slag; and S6, cooling post-treatment is carried out. According to the invention, through synchronous improvement of a formula and a preparation process, direct treatment of molten steel slag, and a method of combining thermal insulation and two-stage cooling phase reconstruction and modification, the content of each component in the steel slag, crystal grains and other phases are controlled, so that the steel slag meets new national standard requirements at the same time; the treated modified material can be used as clinker to be applied to manufacturing of ordinary Portland cement, and the consumption amount is increased. According to the method, energy and resources are utilized at the same time, the resource utilization value and the total consumption amount of the steel slag are increased, and the method has high application value in industry.
本发明属于固废资源化利用技术领域，公开了一种钢渣改性胶凝材料、制备方法及应用，其制备方法包括如下步骤：S1、收集高温钢渣；S2、保温下熔融钢渣组分调控；S3、保温阶段物相改性重构；S4、改性钢渣第一段降温物相重构；S5、改性钢渣第二段降温物相重构；S6、冷却后处理。本发明通过对配方及制备工艺的同步改进，对熔融钢渣的直接处理，经过保温和两阶段降温物相重构结合改性的方法，控制钢渣中各组分的含量、晶粒等物相，使其同时符合新国标要求，使处理后的改性材料能够作为熟料、应用于普通硅酸盐水泥的制造、提高消纳量。本发明同时利用了能源和资源，提高了钢渣资源化利用价值和总消纳量，在工业上具有较高应用价值。
