Abstract

The invention discloses an indoor high-intensity rapid-setting repairing material and a preparation method therefor. The repairing material is prepared from magnesium oxide, fly ash, borax, quartz sands, dihydric phosphate, a magnesium sulfate solution and water through uniform stirring. Compared with the prior art, the repairing material has excellent performances of short setting time, high early stage intensity, good bonding performance, high wear resistance, low dry shrinkage and the like.

Description

technical field [0001] The invention belongs to the field of repair materials, in particular to a high-strength quick-setting repair material for indoor use and a preparation method thereof. Background technique [0002] Concrete is a heterogeneous brittle material formed by mixing sand and gravel aggregates, cement, water and other materials. Due to a series of problems such as concrete construction and its own deformation and constraints, there are a large number of micropores in the hardened concrete. Low tensile strength and lack of toughness. Although these micropores are a kind of harmless cracks, after the concrete is subjected to loads, temperature differences, etc., the microcracks will continue to expand and connect, and eventually form macroscopic cracks that we can see with the naked eye. Once cracks appear in the concrete, It will not only provide convenient conditions for the external erosive medium to enter the concrete, accelerate the damage process, affect ...
