Preparation method and application of self-repairing aggregate
The invention provides a preparation method and application of a self-repairing aggregate, and the method comprises the following steps: adsorbing a sodium silicate solution used as a repairing agent in a lightweight aggregate by adopting a vacuum adsorption method, then forming a protective film on the surface of the sodium silicate solution, and packaging the solution in the lightweight aggregate. The repairing agent in the ceramsite can flow out, and the repairing purpose is achieved. Through the mode, the self-repairing aggregate with an excellent repairing effect is prepared, and the self-repairing aggregate has a relatively high engineering application value.
本发明提供了一种自修复骨料的制备方法及其应用，该方法通过采用真空吸附的方法在轻骨料中吸附作为修复剂使用的硅酸钠溶液，然后在其表面形成保护膜，将溶液封装在轻骨料内部，而在后续应用到混凝土修复中时，可使陶粒中的修复剂流出，实现修复目的。通过上述方式，制得修复效果优异的自修复骨料，具有较高的工程应用价值。
