Preparation method of reducing slag treatment material, reducing slag treatment material and concrete containing reducing slag treatment material
The invention provides a method for preparing a reducing slag treatment material by using electric furnace reducing slag. The reducing slag treatment material takes gamma C2S and/or magnesium-silicon-calcium stone as main components. A method for producing a reduced slag treatment material, which comprises: a component adjustment step for adjusting the component of reduced slag discharged from an electric furnace; and a slow cooling step for producing a reduced slag treatment material that is mainly composed of gammaC2S and/or magnesium-calcium stone using reduced slag. The method comprises: a component adjustment step for adjusting the component of the reduced slag discharged from the electric furnace; and the slow cooling process is used for slowly cooling the reducing slag subjected to component adjustment. Specifically, the reducing slag is subjected to component adjustment in the component adjustment process, so that in the chemical components with the total weight percentage of CaO, SiO2, Al2O3 and MgO being 100%, the weight percentage of CaO is 40-65%, the weight percentage of SiO2 is 15-45%, the weight percentage of Al2O3 is 1-30%, and the weight percentage of MgO is 5-15%. In addition, in a slow cooling step, the reducing slag, the components of which have been adjusted, is slowly cooled in a reducing atmosphere.
本发明提供一种使用电炉还原渣制备还原渣处理材料的方法，该还原渣处理材料以γC2S及/或镁硅钙石为主要成分。还原渣处理材料的制备方法是一种具备成分调整工序及缓慢冷却工序并且使用还原渣制备以γC2S及/或镁硅钙石为主要成分的还原渣处理材料的方法，该成分调整工序对从电炉排出的还原渣进行成分调整；该缓慢冷却工序将成分调整后的还原渣缓慢冷却。具体而言，在成分调整工序对还原渣进行成分调整，以使得在CaO、SiO2、Al2O3、MgO的重量百分比合计为100％的化学成分中，CaO的重量百分比为40‑65％，SiO2的重量百分比为15‑45％，Al2O3的重量百分比为1‑30％，MgO的重量百分比为5‑15％。另外，在缓慢冷却工序，在还原气氛中将成分调整后的还原渣缓慢冷却。
