Electrolytic manganese residue-red mud concrete material as well as preparation method and application thereof
The invention belongs to the technical field of concrete materials, and particularly relates to an electrolytic manganese residue-red mud concrete material as well as a preparation method and application thereof. The electrolytic manganese residue-red mud concrete material is prepared from the following raw material components: electrolytic manganese residue-red mud modified micro powder, a regulator, fine aggregate and coarse aggregate, the electrolytic manganese residue-red mud modified micro powder is prepared from the following raw material components: electrolytic manganese residues, red mud, quick lime, an ammonia nitrogen curing agent and a heavy metal ion stabilizer. Sulfate radicals in the electrolytic manganese residues and alkali in the red mud can be subjected to alkali-double salt excitation with the regulator, the hydration rate and reaction degree of the material are increased, the strength of the cementing material is improved, and generated ettringite and zeolite-like hydration products can block pores of concrete and improve the compactness; the fine aggregate and the coarse aggregate are combined, so that the flexural-tensile strength and the wear resistance of the concrete are improved. In addition, through modification treatment of the electrolytic manganese residues and the red mud, innocent treatment of the electrolytic manganese residues and the red mud is achieved, and pollution of the concrete material to the environment is reduced.
本发明属于混凝土材料技术领域，特别涉及一种电解锰渣‑赤泥混凝土材料及其制备方法和应用。本发明电解锰渣‑赤泥混凝土材料的原料组分包括电解锰渣‑赤泥改性微粉、调整剂、细骨料、粗骨料；电解锰渣‑赤泥改性微粉的原料组分包括电解锰渣、赤泥、生石灰、氨氮固化剂、重金属离子稳定剂。本发明电解锰渣中的硫酸根和赤泥的碱，可以和调整剂发生碱‑复盐激发，加快材料的水化速率和反应程度，提高胶凝材料的强度，生成的钙矾石和类沸石的水化产物可封堵混凝土的孔隙，提高密实度；并结合细骨料、粗骨料，提高混凝土的弯拉强度和耐磨性。另外，通过对电解锰渣和赤泥进行改性处理，实现电解锰渣和赤泥的无害化处理，降低混凝土材料对环境的污染。
