Method for preparing high-performance admixture by exciting carbonization activity of steel slag through additive
The invention discloses a method for preparing a high-performance admixture by exciting carbonization activity of steel slag through an additive, and belongs to the technical field of industrial waste residue utilization. The related operation process comprises the following steps: crushing and grinding a steel slag raw material block to obtain steel slag powder; and uniformly mixing the steel slag powder with an additive solution according to a certain proportion to obtain the high-carbonization active steel slag powder. According to the method, the steel slag carbon capture rate under most carbonization conditions can be increased, and the steel slag carbon capture rate is increased by introducing the additive, so that the cost is low, the effect is remarkable, and the method is easy to implement in actual production. The excited steel slag can absorb more carbon dioxide and generate more gelling components, so that the hydration activity of the steel slag is indirectly improved. In addition, the catalyst improves the carbonization efficiency of the steel slag, so that free calcium oxide and carbon dioxide in the steel slag react more sufficiently, unstable components in the steel slag are reduced, and the volume stability of the steel slag is improved. According to the preparation method of the carbonized steel slag admixture, the steel slag carbon capture rate can be effectively increased.
一种外加剂激发钢渣碳化活性以制备高性能掺合料的方法，属于工业废渣利用技术领域。其涉及的操作过程如下：对钢渣生料块进行破碎，粉磨以得到钢渣粉；将钢渣粉以一定比例与外加剂溶液均匀混合得到高碳化活性钢渣粉。本发明的方法可以提升大部分碳化条件下的钢渣捕碳率，并且通过引入外加剂的手段提升钢渣捕碳率不仅成本低、效果显著并且在实际生产中容易实现。经过激发后的钢渣可以吸收更多的二氧化碳并且产生更多具有胶凝性的成分，间接提升钢渣的水化活性。另外，催化剂提升了钢渣的碳化效率，从而使得钢渣中的游离氧化钙与二氧化碳反应更加充分，降低钢渣中的不安定组分，提高钢渣的体积安定性。本发明提出的碳化钢渣掺合料制备方法可以有效提升钢渣捕碳率。
