Preparation method of impervious admixture for concrete mortar
The invention relates to a preparation method of an impervious admixture for concrete mortar, and belongs to the technical field of mortar admixtures. The concrete is prepared from polyvinyl alcohol, stearic acid, ammonia water, magnesium lignosulfonate, a thickening agent, an air entraining agent, a surfactant, a biological modifier, a water reducing agent, an expanding agent, a retarder, ionized water, ferric trichloride, hydrogen peroxide, sodium ethyl silicate, latex powder and cellulose. The invention provides the preparation method of the anti-permeability admixture for the concrete mortar, and the anti-permeability admixture can cut off capillary channels of the mortar to inhibit the shrinkage of the mortar, so that the anti-permeability capability of the mortar is improved, the microstructure of the mortar is improved, the anti-permeability capability of the mortar is improved, and the preparation method has the advantages of simple production process, low cost and the like.
本发明涉及一种混凝土砂浆的抗渗外加剂制备方法，属于砂浆外加剂技术领域。其包括：聚乙烯醇、硬脂酸、氨水、木质磺酸镁、增稠剂、引气剂、表面活性剂、生物改性剂、减水剂、膨胀剂、缓凝剂、离子水、三氯化铁、过氧化氢、乙基硅酸钠、乳胶粉、纤维素。本发明提供一种混凝土砂浆的抗渗外加剂制备方法，其能够切断砂浆的毛细管道起到抑制砂浆收缩性，从而提高砂浆的抗渗能力能具有改善砂浆的微观结构，提高其抗渗能力，且生产工艺简单，成本低等优点。
