Preparation method and application of industrial carbonized steel slag
The invention relates to a preparation method and application of industrial carbonized steel slag. The preparation method comprises the following steps: preparing steel slag micro powder, preparing aerated blocks, carbonizing the aerated blocks and preparing carbonized steel slag powder. The prepared carbonized steel slag powder is used for preparing an SMA asphalt mixture. By adopting the preparation process of grinding the steel slag powder into powder, preparing the aerated block from the steel slag powder, carbonizing and re-grinding, the purposes of large-scale and rapid carbonization of the steel slag powder and high carbon dioxide absorption amount can be realized at the same time, so that low-cost and industrial large-scale production can be realized; the carbonized steel slag powder is added into the asphalt to replace mineral powder, the water stability of the prepared asphalt mixture is improved by 18%, and the purpose of safe, low-carbon and large-scale treatment of the steel slag can be achieved; the asphalt is flexible and oily substance, the stability problem does not exist after the carbonized steel slag powder is applied, and safety and reliability are achieved.
本发明涉及一种工业化碳化钢渣的制备方法及其应用，制备方法包括以下步骤：制备钢渣微粉、制备加气块、碳化加气块、制备碳化钢渣粉；制备的碳化钢渣粉用于制备SMA沥青混合料。采用钢渣粉磨成粉、钢渣粉制备加气块、碳化、再磨粉的制备工艺，可以同时实现大规模、快速碳化钢渣粉以及高的二氧化碳吸收量的目的，从而可实现低成本、工业化大规模生产；将碳化后的钢渣粉加入到沥青里代替矿粉，制备沥青混合料水稳定性提高18%，可实现安全、低碳、大规模处置钢渣的目的；沥青为柔性且为油性物质，碳化钢渣粉应用后不存在安定性问题，安全可靠。
