| description | The invention discloses a concrete crack repairing method. The concrete crack repairing method comprises the following steps of cleaning a crack: detecting the depth and width of the crack by using equipment, then cleaning the ground near the crack, and when an opening in the top of the crack is smaller than 5mm, digging a groove with the width of 0.5-1cm along the crack, cleaning the inner wall of the crack by using a high-pressure water gun and a high-pressure air gun; preparing slurry: mixing and preparing a filling material according to a proportion, wherein the filling material is prepared from 50 to 55 parts of cement, 25 to 28 parts of fly ash, 10 to 12 parts of quartz sand, 2 to 5 parts of epoxy resin glue, 1 to 1.2 parts of redispersible latex powder, 0.5 to 1.5 parts of a water reducing agent and 0.2 to 0.6 part of a retarder; cement, fly ash, silica fume, epoxy resin glue, redispersible latex powder, the water reducing agent, the retarder and the like are used for preparing a high-viscosity filling |
