Steel slag-based solid waste cementing material and composition design method
The invention discloses a steel slag-based solid waste cementing material and a composition design method, and belongs to the technical field of steel slag resource utilization. The formula of the steel slag-based solid waste cementing material comprises the following components in percentage by mass: 20-35% of steel slag, 50-65% of mineral slag, 2-10% of desulfurized gypsum and 10% of cement. According to the method, the optimal alkalinity value is determined by detecting the content of CaO, SiO2, Al2O3 and MgO in the raw material steel slag and slag, the optimal dosage of the steel slag and slag is calculated according to the relationship between the alkalinity value and the alkalinity coefficient, and then the optimal proportion is obtained, so that the efficiency of ingredient ratio design is improved, and the time cost is saved.
本发明公开一种钢渣基固废胶凝材料及组成设计方法，属于钢渣资源化利用技术领域。所述钢渣基固废胶凝材料的配方按照质量百分比计，包括：钢渣20‑35％，矿渣50‑65％，脱硫石膏2‑10％和水泥10％。本发明通过检测原料钢渣和矿渣中CaO、SiO2、Al2O3及MgO的含量来确定最佳碱度值，再根据碱度值与碱性系数之间的关系计算出钢渣和矿渣的最佳用量，进而得出最佳配比，从而提高配料比设计的效率，节约时间成本。
