Nano-alumina-doped steel slag cement composite cementing material and preparation method thereof
The invention relates to a nano-alumina-doped steel slag cement composite cementing material and a preparation method thereof, and belongs to the technical field of comprehensive utilization of steel slag. The preparation method comprises the following steps: crushing and grinding large steel slag, and screening and grading to obtain steel slag powder of which the particle size is less than 0.08 mm; weighing raw materials according to the mass, wherein the raw materials used by the neat paste sample comprise steel slag, cement, nano aluminum oxide and water; the mortar sample is prepared from the following raw materials: steel slag, cement, nano aluminum oxide, water and standard sand; and adding the required raw materials according to the steps, and uniformly stirring to obtain a corresponding neat paste sample and a mortar sample. The method can significantly improve the stability of the steel slag cement composite cementing material, can significantly improve the strength of the steel slag cement composite cementing material, can be used for improving the influence of steel slag as a cement-based cementing material active admixture on the stability and strength of the cement-based cementing material, and is simple to operate and high in practicability.
本发明涉及一种掺纳米氧化铝钢渣水泥复合胶凝材料及制备方法，属于钢渣的综合利用的技术领域。本发明的制备方法包括：将大块钢渣进行破碎、粉磨，通过筛分分级得到粒径小于0.08mm的钢渣粉；按质量称取原料，净浆试样所用原料：钢渣、水泥、纳米氧化铝、水；胶砂试样所用原料：钢渣、水泥、纳米氧化铝、水、标准砂；按步骤加入所需原料，搅拌均匀后，得到相应的净浆试样和胶砂试样。本发明可以显著改善钢渣水泥复合胶凝材料的安定性问题，并可以显著提高其强度，可用于改善钢渣作为水泥基胶凝材料活性掺合料对其安定性和强度的影响，且操作简单，实用性强。
