High-toughness quick-setting repair mortar and preparation method thereof
The invention discloses a high-toughness quick-setting repair motor and a preparation method thereof, and belongs to the technical field of bridge crack repairing materials. The high-toughness quick-setting repairing motor comprises the following raw materials by weight: 90-110 parts of superfine cement, 40-70 parts of water, 5-20 parts of a polymer styrene-acrylic emulsion, 1-3 parts of nano silica, 0.5-2.0 parts of triethanolamine, 2-8 parts of a steel bar corrosion inhibitor. and 0.2-0.5 part of a polycarboxylic acid water reducing agent; wherein 0.2-2% of chopped steel fiber is added into each cubic meter of superfine cement. The cement concrete bridge crack repairing material which is high in toughness, high in strength and fast in setting is prepared, on one hand, cracks are poured and maintained under the condition that traffic is not interrupted, on the other hand, high use durability of the repaired cracks is guaranteed, and the cement concrete bridge crack repairing material has remarkable social and economic benefits.
本发明公开了一种高韧快凝修补胶浆及其制备方法，属于桥梁裂缝修补材料技术领域，所述高韧快凝修补胶浆原料按照重量份数计，包括以下组分：超细水泥90～110份，水40～70份，聚合物苯丙乳液5～20份，纳米二氧化硅1～3份，三乙醇胺0.5～2.0份，钢筋阻锈剂2～8份，聚羧酸减水剂0.2～0.5份；每立方米超细水泥添加短切钢纤维0.2～2％；制备了一种高韧性、高强度、快凝结的水泥混凝土桥梁裂缝修补材料，一方面实现了不中断交通条件下对裂缝进行灌缝和维修，另一方面也确保了修复之后的裂缝良好的使用耐久性，具有显著的社会经济效益。
