The invention provides an admixture for a high-sulfur tailing filling cementing material and a production process of the admixture, and relates to the technical field of chemical materials, the admixture for the high-sulfur tailing filling cementing material comprises the following components: superfine slag powder, ground fly ash, sodium carbonate and a polycarboxylate superplasticizer (solid content is 40%); when the admixture for the high-sulfur tailing filling cementing material is mainly used for filling high-sulfur tailings, the admixture and cement are added together or added into the cement in advance, so that the performance of a filling body is improved, the strength of the filling body is mainly improved, the stability of the strength is maintained, and meanwhile, the filling cost of the high-sulfur tailings can be reduced.
本发明提供一种高硫尾矿充填胶凝材料用外加剂及其生产工艺，涉及化工材料技术领域，所述高硫尾矿充填胶凝材料用外加剂组分包括矿渣微粉、磨细粉煤灰、碳酸钠，聚羧酸减水剂(固含40％)；高硫尾矿充填胶凝材料用外加剂主要用于高硫尾矿充填时，通过与水泥一起加入或者提前加在水泥里面，从而改善充填体的性能，主要是提高充填体的强度并保持强度的稳定性，同时可以降低高硫尾矿的充填成本。
