Artificial steel slag aggregate and preparation method and application thereof
The invention discloses an artificial steel slag aggregate and a preparation method and application thereof. The preparation method comprises the following steps: step 1, grinding steelmaking tailingsby using a ball mill to obtain uniform steel slag powder; 2, weighing Portland cement, an admixture fine powder and steel slag powder, and conducting uniform mixing to obtain an aggregate raw material; 3, preparing an additive aqueous solution; 4, putting the aggregate raw material into a ball forming mill, and uniformly spraying the additive aqueous solution prepared in the step 3 to form balls,so as to obtain spherical artificial steel slag aggregate; step 5, putting the pelletized aggregate into a closed environment or a natural environment for pre-curing; and step 6, putting the pre-cured aggregate into a carbonization device for carbonization treatment to finally prepare the artificial steel slag aggregate. The artificial steel slag aggregate prepared by the method can achieve the goals of safety and high strength, the crushing index of the aggregate can reach 9.26% and reach the I-grade aggregate use standard, the production process is simple, the solid waste is recycled, the carbon dioxide is absorbed and cured, and the artificial steel slag aggregate is free of burning, low-carbon and environment-friendly.
人造钢渣骨料及其制备方法和应用，步骤一.使用球磨机对炼钢尾渣进行粉磨，得到均匀钢渣粉末；步骤二.称取硅酸盐水泥、掺合料细粉和钢渣粉末，混合均匀，得到骨料原料；步骤三.配制外加剂水溶液；步骤四.将骨料原料放入成球机，均匀喷洒步骤三配制的外加剂水溶液成球，得到球状人造钢渣骨料；步骤五.将成球的骨料放入密闭环境或自然环境中进行预养护；步骤六.将预养护后的骨料放入碳化装置中进行碳化处理，最终制得人造钢渣骨料。通过本方法制备的人造钢渣骨料，可以实现骨料安全高强的目标，骨料压碎指标可以达到9.26%，达到Ⅰ级骨料使用标准，本发明生产工艺简单，资源化利用了固体废弃物，吸收固化二氧化碳，免烧，低碳环保。
