The invention belongs to the technical field of concrete admixtures, and discloses a slow-release concrete performance improver. The cement grinding aid is prepared from the following raw materials inparts by weight: 1-3 parts of sodium p-benzylaminobenzenesulfonate, 1-3 parts of glycidyl trimethyl ammonium chloride, 1-3 parts of sodium methyldisulfonate, 1-5 parts of sodium lactate, 10-20 partsof carboxylic acid polymer, 0.2-2 parts of polyvinyl alcohol, 0.001-0.05 part of petroleum sodium sulfonate and 80-100 parts of asbestos tailing acid leaching residues. The characteristic that the asbestos tailing acid leaching residues contain a large amount of SiO2 with high activity and high specific surface area is ingeniously utilized, other performance improving substances are fully adsorbedby utilizing the asbestos tailing acid leaching residues, the asbestos tailing acid leaching residues are slowly released in the concrete stirring process, and the working state of concrete is kept stable for a long time.
本发明属于混凝土外加剂技术领域，公开了一种缓释型混凝土性能改善剂，由以下重量分数的原料组成：对苄氨基苯磺酸钠1‑3份、缩水甘油三甲基氯化铵1‑3份、甲基二磺酸钠1‑3份、乳酸钠1‑5份、羧酸聚合物10‑20份、聚乙烯醇0.2‑2份、石油磺酸钠0.001‑0.05份、石棉尾矿酸浸渣80‑100份。本发明巧妙利用石棉尾矿酸浸渣中含有大量高活性高比表面积的SiO2的特点，利用其充分吸附其他性能改善物质，在混凝土搅拌过程中缓慢释放，长时间保持混凝土的工作状态稳定。
