High-strength and high-durability cement-based premix material and preparation method thereof
The invention discloses a high-strength and high-durability cement-based premix material and a preparation method thereof. The premix material comprises the following components in parts by weight: 80-85 parts of dry powder A, 10-15 parts of slurry B and 6-8 parts of toughening material C. In the using process, the dry powder A and the slurry B are sequentially poured into a stirring device and stirred for 2 minutes, then the toughening material C is added, and the mixture can be applied after being continuously stirred for 2 minutes. The application problems that the ratio design is difficult to be accurate, the dispersion is difficult to control and the like in the construction process of the existing ultrahigh-strength cement-based materials such as UHPC can be solved, and the material has the characteristics of convenience and rapidness in application, good construction performance, stable strength, good durability and the like, and can be widely applied to engineering such as reinforcement and repair of key parts such as bridges, buildings and the like.
本发明公开了一种高强度高耐久水泥基预混材料及其制备方法，该预混材料的组分及相应的重量份数为：干粉料A 80～85份，浆料B 10～15份，增韧料C 6～8份。使用过程中，将干粉料A和浆料B依次倒入搅拌装置，搅拌2分钟后加入增韧料C，继续搅拌2分钟后即可应用。本发明可以解决现有UHPC等超高强水泥基材料在施工过程中配比设计难以精确，分散难以控制等应用难题，具有应用方便快捷、施工性能好、强度稳定、耐久性好等特点，可广泛应用于桥梁、建筑等关键部位的加固、修补等工程。
