Cement-based repair material and repair method for freeze-thaw damaged concrete
The invention provides a cement-based repair material for freeze-thaw damaged concrete and a repair method, and relates to the technical field of building materials. Specifically, the cement-based repair material comprises a binding layer material, a ceramsite layer material and a protective layer material, the binding layer is prepared from cement, silica fume, metakaolin, quartz sand, nano SiO2, nano Fe2O3, a water reducing agent and water; the ceramsite layer material comprises ceramsite; and the protective layer material comprises cement, silica fume, metakaolin, quartz sand, polypropylene plastic steel fibers, a water reducing agent and water. A damaged part is treated, and then a binding layer, a ceramsite layer and a protective layer are sequentially arranged for repairing. After the repairing material and the repairing method are adopted for repairing, the bonding strength of new and old interfaces is high, the freezing resistance is good, the tensile strength of a protective layer is high, further freeze-thaw damage of an old structure can be effectively prevented, and the service life is prolonged.
本发明提供了一种冻融损伤混凝土的水泥基修复材料及修复方法，涉及建筑材料技术领域。具体而言，所述水泥基修复材料包括结合层材料、陶粒层材料和保护层材料；所述结合层材料包括水泥、硅灰、偏高岭土、石英砂、纳米SiO2、纳米Fe2O3、减水剂和水；所述陶粒层材料包括陶粒；所述保护层材料包括水泥、硅灰、偏高岭土、石英砂、聚丙烯塑钢纤维、减水剂和水。通过对受损部位进行处理，然后依次设置结合层、陶粒层和保护层的方法进行修复。采用本发明的修复材料和修复方法修复后，新旧界面粘结强度高、抗冻性好、保护层抗拉强度高，可有效阻止旧结构进一步冻融损伤，延长使用寿命。
