Ardealite-red mud-slag composite cementing material for solidifying lake sediment characteristics and mechanism research
The invention discloses an ardealite-red mud-slag composite cementing material solidified lake sediment characteristic and mechanism research, which comprises the following steps: respectively grinding ardealite and red mud for 50 min through a dry grinding device, grinding slag for 70 min through the dry grinding device, mixing the ardealite, the red mud and the slag according to the percentage ratio, and uniformly mixing the ardealite, the red mud and the slag to obtain the ardealite-red mud-slag composite cementing material solidified lake sediment. The preparation method comprises the following steps: mixing the raw materials, adding a cementing material, mixing, putting the mixture into a high-efficiency water reducing agent with the total mass of 0.3%, mixing again, carrying out low-speed stirring and high-speed stirring by using equipment for mixing, putting the prepared sample into a model for molding, respectively maintaining for 3 days, 7 days and 28 days after molding, and carrying out strength test. However, the utilization rate of the phosphogypsum is not high, so that the phosphogypsum, the red mud and the slag are compounded, prepared and molded, the compressive strength of the material is tested, and the purpose of resource utilization is achieved.
本发明公开了一种磷石膏‑赤泥‑矿渣复合胶凝材料固化湖泊底泥特性与机理研究，包括以下步骤：将磷石膏和赤泥通过干式研磨设备分别研磨50min，在将矿渣通过干式研磨设备研磨70min，而后按照百分比配比将磷石膏、赤泥、矿渣混合，并加入胶凝材料混合，而后将上述混合物置于总质量为0.3%的高效减水剂中再次混合，其中混合所用设备需先低速搅拌在高速搅拌，而后将制得的样品置于模型中成型，成型后分别养护3d、7d、28d，并进行强度测试，由于磷肥生产会产生大量磷石膏，但磷石膏的利用率并不高，因此本发明将磷石膏、赤泥、矿渣通过复合制备成型，并测试其抗压强度，为实现资源化利用的目的。
