Additive for promoting carbonization degree of steel slag and method for promoting carbonization degree of steel slag
The invention provides an application of an admixture in a preparation process of a steel slag-based carbonized product. The additive comprises hollow fibers and a natural porous material. The invention also provides an additive for promoting the carbonization degree of the steel slag. According to the invention, materials with different pore diameters and different dimensions are specially adopted to design the admixture, and the admixture comprises hollow fibers, a natural porous material and a composite material formed by the hollow fibers and the natural porous material. The additive provided by the invention is combined with a corresponding use method, so that the alkalinity of the steel slag-based carbonized product can be reduced, the stability of the steel slag-based carbonized product can be improved, the carbonization depth of the steel slag-based product can be obviously improved, the stability of the steel slag-based product can be further improved, and particularly, the carbonization depth of a dense-graded steel slag-based product can be increased. And the preparation method and the use are simple, the conditions are mild, the controllability is good, and industrial scale production, popularization and application are more facilitated.
本发明提供了外加剂在钢渣基碳化制品制备过程中的应用；所述外加剂包括中空纤维和天然多孔材料。本发明还提供了一种用于促进钢渣碳化程度的外加剂。本发明特别采用不同孔径和不同维度的材料设计了上述外加剂，包括中空纤维、天然多孔材料以及二者形成的复合材料。采用本发明提供的添加剂结合相应的使用方法，能够降低钢渣基碳化制品的碱度，改善其安定性，还能明显改善钢渣基制品的碳化深度，进一步增加其安定性，特别是能够增加密级配钢渣基制品的碳化深度。而且制备方法和使用简单，条件温和，可控性好，更加有利于工业化规模生产和推广应用。
