Method for preparing steel slag product by synergistically enhancing mineral carbonization effect
A method for preparing a steel slag product by synergistically enhancing mineral carbonization comprises the following steps: (1) uniformly mixing a chelating agent and water in proportion to obtain a chelating agent solution; (2) taking the chelating agent solution in the step (1) as mixing water, and uniformly mixing the chelating agent solution with steel slag powder in proportion to obtain a mixed steel slag material; (3) doping a CO2 absorbent into the steel slag material mixed in the step (2) in proportion, and uniformly stirring to obtain steel slag slurry; (4) injecting the steel slag slurry in the step (3) into a mold, performing compression molding, and demolding to obtain a steel slag product blank; and (5) putting the steel slag product blank in the step (4) into a carbonization reaction kettle, and carrying out carbon sequestration maintenance to obtain the carbonized steel slag product. The carbonization degree of the steel slag product can be improved, so that more CO2 can be cured in the carbonization process of the product, and the environmental benefits of the product are improved; the performance of the carbonized steel slag product can be greatly improved.
一种协同增强矿物碳化作用制备钢渣制品的方法，包括以下步骤：（1）将螯合剂与水按比例混合均匀，得到螯合剂溶液；（2）将步骤（1）中螯合剂溶液作为拌合水，并与钢渣粉按比例混合均匀，得到混合的钢渣材料；（3）将CO2吸收剂按比例掺入步骤（2）中混合的钢渣材料中，并搅拌均匀，得到钢渣浆体；（4）将步骤（3）中钢渣浆体注入模具，并压制成型、脱模，得到钢渣制品坯体；（5）将步骤（4）中钢渣制品坯体放入碳化反应釜，进行固碳养护，得到碳化钢渣制品。本发明能提高钢渣制品的碳化程度，使得制品在碳化过程中能够固化更多CO2，提高制品环境效益；能够大幅改善碳化钢渣制品的性能。
