Hydraulic concrete high-performance repair mortar and construction process thereof
The invention relates to the technical field of hydraulic concrete repairing, and discloses hydraulic concrete high-performance repairing mortar and a construction technology thereof, and the construction technology comprises the following technological processes: base surface treatment, interface treating agent preparation, interface treating agent brushing, hydraulic concrete high-performance repairing mortar preparation, high-performance mortar repairing and maintenance. In order to increase the freezing resistance of the hydraulic concrete repair mortar, the cement mortar is modified by doping the polymer acrylic emulsion and the instant rubber powder, and a continuous film is formed in the mortar, so that an anti-seepage effect can be achieved, the freezing resistance is further improved, the workability of the mortar is improved, the bonding strength and the abrasion resistance can be improved at the same time, and the service life of the hydraulic concrete repair mortar is prolonged. The shrinkage is reduced; the anti-cracking effect is improved. Meanwhile, the freezing resistance of the mortar is improved by adding an air entraining and water reducing agent. In order to realize the abrasion resistance of the repairing mortar, the abrasion resistance is improved by doping the silicon powder and the basalt fiber.
本发明涉及水工混凝土修补技术领域，公开了一种水工混凝土高性能修补砂浆及其施工工艺，包括一下工艺流程：基面处理、配制界面处理剂、涂刷界面处理剂、配制水工混凝土高性能修补砂浆、高性能砂浆修补、养护。本发明为实现水工混凝土修补砂浆增加抗冻性，通过掺入聚合物丙烯酸乳液和速溶胶粉对水泥砂浆进行改性，在砂浆内部形成连续性膜，可起到防渗作用，进而提高抗冻性能，同时改善了砂浆和易性，同时可提高粘结强度和抗冲磨性能，减少收缩提高抗裂作用。同时也通过掺加引气减水剂来提高砂浆抗冻性。为实现修补砂浆具有抗冲磨性能，通过掺入硅粉和玄武岩纤维提高抗冲磨性能。
