Copper-nickel smelting slag-based cementing material and preparation method thereof
The invention provides a copper-nickel smelting slag-based cementing material and a preparation method thereof, and the preparation method comprises the following steps: (1) weighing raw materials, comprising 20-25% of copper-nickel ore smelting slag, 10-15% of cement, 5-10% of phosphorus slag, 4-9% of waste glass powder, 6-10% of attapulgite clay, 2-5% of nano clay, 5-10% of sodium hydroxide, 1-2% of a water reducing agent, 0.1-0.5% of a dispersing agent and the balance of water. And (2) uniformly mixing the raw materials, putting into a wet mill, keeping the temperature at 50-60 DEG C in the grinding process, grinding for 70-90 minutes, and filtering a grinding body to obtain the copper-nickel smelting slag-based cementing material. According to the copper-nickel smelting slag-based cementing material provided by the invention, the copper-nickel ore smelting slag and the phosphorus slag are utilized, and a plurality of materials are supplemented and are synergistically compounded, so that the setting time of cement can be remarkably shortened, and the early mechanical property of a cement-based material can be enhanced.
本发明提供了一种铜镍冶炼渣基胶凝材料及其制备方法，所述制备方法包括以下步骤：(1)称取原材料，按质量百分数计，包括铜镍矿冶炼渣20‑25％、水泥10‑15％、磷渣5‑10％、废弃玻璃粉4‑9％、凹凸棒石黏土6‑10％、纳米黏土2‑5％、氢氧化钠5‑10％、减水剂1‑2％、分散剂0.1‑0.5％，剩余为水；(2)将原料混合均匀放入湿磨机中，使得研磨过程温度保持在50‑60℃，研磨70‑90分钟，过滤研磨体，得到铜镍冶炼渣基胶凝材料。本发明提供了一种铜镍冶炼渣基胶凝材料，利用铜镍矿冶炼渣、磷渣，并辅以多种材料，协同复配，可以显著降低水泥的凝结时间，增强水泥基材料的早期力学性能。
