Nano metakaolin modified cement mortar interface agent as well as preparation method and application thereof
The invention relates to a nano metakaolin modified cement mortar interface agent as well as a preparation method and application thereof, and belongs to the technical field of building materials. The interface agent is prepared from the following raw materials: a cementing material, standard sand and water in a mass ratio of 1: 1: 0.44; the cementing material comprises Portland cement and nano metakaolin, and the mass percentage content of the nano metakaolin is 3%. The nano metakaolin and the water reducing agent are combined for use, the porosity of a transition area of a bonding interface of new and old concrete is reduced by utilizing the filling effect of the nano material, the bonding performance of the new and old concrete is improved by improving the bonding performance of the nano material, and meanwhile, the workability of cement paste is improved under the effect of the water reducing agent.
本发明涉及一种纳米偏高岭土改性水泥砂浆界面剂及其制备方法和应用，属于建筑材料技术领域。所述界面剂由下列质量比的原料组成：胶凝材料：标准砂：水＝1：1：0.44；所述胶凝材料包括硅酸盐水泥和纳米偏高岭土，其中纳米偏高岭土的质量百分含量为3％。本发明利用纳米偏高岭土和减水剂组合使用，不仅利用纳米材料的填充作用降低了新旧混凝土粘结界面过渡区的孔隙率，且依靠其粘结性能的提升改善了新老混凝土的粘结性能同时在减水剂的作用下提高了水泥浆体的和易性。
