Cement admixture prepared from electrolytic manganese residues and preparation method of cement admixture
The invention discloses a cement admixture prepared from electrolytic manganese residues and a preparation method of the cement admixture, and belongs to the technical field of solid waste resource utilization. The raw materials for preparing the cement admixture from the electrolytic manganese residues are prepared from the following components in parts by weight: 60-80 parts of electrolytic manganese residues from which ammonia nitrogen and manganese are removed, and 20-40 parts of a water reducing agent. Wherein the raw materials for removing the ammonia nitrogen and the manganese in the electrolytic manganese residues comprise the following components in parts by mass: 16-45 parts of the electrolytic manganese residues, 4-10 parts of citric acid and 45-80 parts of pure water. The preparation method for preparing the cement admixture from the electrolytic manganese residues comprises the following steps: removing ammonia nitrogen and manganese in the electrolytic manganese residues in a leaching manner through mechanical oscillation, and then mixing the electrolytic manganese residues without the ammonia nitrogen and the manganese with the water reducing agent according to the formula proportion to prepare the cement admixture. The cement admixture prepared by the method is good in retarding performance and high in water-reducing rate.
本发明公开了一种电解锰渣制备水泥外加剂及其制备方法，属于固体废弃物资源化利用的技术领域。一种电解锰渣制备水泥外加剂所需的原料由以下重量份配比的组分制备：脱除氨氮和锰的电解锰渣60～80份、减水剂20～40份。其中脱除电解锰渣中氨氮和锰所需的原料包括以下质量份数的组分：电解锰渣16～45份、柠檬酸4～10份、纯水45～80份。一种电解锰渣制备水泥外加剂的制备方法包括以下步骤：通过机械振荡以浸取的方式将电解锰渣中的氨氮和锰去除，随后将脱除氨氮和锰的电解锰渣与减水剂按照上述配方比例混合制成水泥外加剂。本发明制备的水泥外加剂缓凝性能良好、减水率高。
