Method for preparing all-solid waste cementing material from superfine powder material and application of all-solid waste cementing material
The invention discloses a method for preparing an all-solid-waste cementing material from a superfine powder material and application of the all-solid-waste cementing material, the all-solid-waste cementing material comprises superfine slag powder, superfine steel slag powder and desulfurized gypsum according to the mass part ratio of (50-60): (30-40): (5-15), the specific surface area of the superfine slag powder is larger than or equal to 700 m < 2 >/kg, the specific surface area of the superfine steel slag powder is larger than or equal to 700 m < 2 >/kg, and the specific surface area of the desulfurized gypsum is larger than or equal to 400 m < 2 >/kg. According to the all-solid-waste cementing material, the steel slag is subjected to a hydration reaction to generate alkaline substances, the alkaline substances are combined with the doped gypsum component to jointly excite active materials in the slag to form various gels and ettringite substances, finally, a hydraulic cementing material with certain strength is formed, meanwhile, the slag and the steel slag are ground into superfine powder, and the whole-solid-waste cementing material is prepared. The porosity of the all-solid waste cementing material is effectively reduced, and the strength of the material is improved.
本发明公开了一种超细粉体材料制备全固废胶凝材料的方法及其应用，全固废胶凝材料包括质量份之比为（50‑60）：（30‑40）：（5‑15）的矿渣微粉、钢渣微粉、脱硫石膏，其中矿渣微粉的比表面积≥700㎡/kg、钢渣微粉的比表面积≥700㎡/kg，脱硫石膏的比表面积≥400㎡/kg。该全固废胶凝材料通过将钢渣水化反应产生碱性物质，结合掺入的石膏成分共同激发矿渣中的活性材料形成各类凝胶和钙矾石物质，最终形成具有一定强度的水硬性胶凝材料，同时还将矿渣和钢渣磨成超细的粉末，有效降低了全固废胶凝材料的孔隙率并提升了材料的强度。
