High-sulfur steel slag solid waste cementing material and preparation method thereof
The invention discloses a high-sulfur steel slag solid waste cementing material and a preparation method thereof. The high-sulfur steel slag solid waste cementing material is prepared from the following components in percentage by mass: 35-45% of steel slag, 25-35% of slag, 0-15% of fly ash, 10-15% of byproduct gypsum, 10-15% of cement and water which accounts for 30-40% of the total mass of the components. The preparation method comprises the following steps: weighing the raw materials according to the corresponding weight, fully and uniformly mixing, adding water, stirring in a cement paste stirrer for 3-4 minutes, pouring the slurry obtained by stirring into a mold, compacting for 30-45 seconds on a cement mortar compacting table, standing for 1 day for molding, demolding a molded sample, and carrying out standard curing to obtain the product. No additional alkaline excitant such as water glass and NaOH is added, and meanwhile, the long-term strength is high, and the volume stability is good.
本发明公开了一种高硫型钢渣固废胶凝材料及其制备方法,由按质量百分含量的钢渣35~45%、25~35%矿渣、0~15%粉煤灰、10~15%副产石膏、10~15%水泥,以及上述组份质量总和30~40%的水组成。各原料按照配比称量相对应的重量,然后充分混合均匀后加入水,随后在水泥净浆搅拌机中搅拌3~4分钟,将搅拌所得浆料倒入模具中,在水泥胶砂振实台振实30~45s,模具静置1天成型,成型样品脱模后,进行标准养护即得。本申请无任何外加碱性激发剂如水玻璃,NaOH等,同时后期强度高,体积稳定性良好。
