Electrolytic manganese residue-based active cementing material and preparation method thereof
The invention discloses an electrolytic manganese residue-based active cementing material and a preparation method thereof, and belongs to the technical field of solid waste resource utilization. Raw materials including electrolytic manganese residues, red mud and carbide slag are dried, crushed and evenly mixed and then calcined at the temperature of 1080-1180 DEG C, a calcined product is cooled and ground, and the electrolytic manganese residue-based active cementing material is obtained. The preparation process of the electrolytic manganese residue-based active cementing material meets the requirements specified by the HJ 1241-2022 Technical Specification for Manganese Slag Pollution Control. The performance of the obtained cementing material product meets the requirements of GB/T 18046-2017 Granulated Blast Furnace Slag Powder Used in Cement, Mortar and Concrete S75 slag powder, and the cementing material can replace part of cement to be used in concrete, so that efficient resource utilization of solid wastes such as electrolytic manganese residues and the like is realized.
本发明公开了一种电解锰渣基活性胶凝材料及其制备方法，属于固废资源化利用技术领域。将包括电解锰渣、赤泥和电石渣在内的原料经过烘干、破碎、混匀后，在1080～1180℃温度下煅烧，煅烧产物经过冷却和研磨，即得电解锰渣基活性胶凝材料，其制备过程符合HJ 1241‑2022《锰渣污染控制技术规范》规定的要求，且所得胶凝材料产品性能符合GB/T 18046‑2017《用于水泥、砂浆和混凝土中的粒化高炉矿渣粉》S75矿渣粉的要求，可代替部分水泥用于混凝土，实现了电解锰渣等固废的高效资源化利用。
