Description

technical field [0001] The invention relates to the technical field of grouting material, in particular to a high-performance cracking grouting material and its application. Background technique [0002] In recent years, the transportation industry has developed rapidly, and the total mileage of national highways has reached more than 4 million kilometers. With the increase of the service life of the highway and the increase of various complex geological environments and vehicle loads, the damage of highway bridges is becoming more and more serious. In order to extend the service life of highway bridges and ensure the normal traffic capacity of highways, we urgently need to find a comprehensive and excellent concrete crack repair material. There are many kinds of existing concrete crack repair materials, including glue injection and cement-based materials. However, due to the monopoly of raw materials, formulas and preparation technology by individual large international co...
