Various methods of how to repair the unevenness of concrete external wall
The repair method is as follows: 1. Pockmarked surface: After the pockmarked surface is fully watered and wetted, the mortar is repaired with polymer on the same day, and the pockmarked surface is smooth and the color is consistent. Moisturize with straw curtain or straw bag after repair.
2. Leaked reinforcement: How to repair the uneven concrete external wall after washing away the leaked reinforcement on the surface? Epoxy resin repair mortar shall be used to smooth the leaking part. If the rebar leakage is deep, the weak concrete and protruding particles should be chiseled and removed. After cleaning, the special and special high-strength epoxy mortar shall be packed tightly and carefully maintained.
3. Honeycomb: For small batteries, after cleaning, use Wuji Zhi Zhi? Polymer repair mortar to make a smooth, larger honeycomb, first chisel to loose stones and rinse clean, with a special afternoon Zhi Zhi? High-strength epoxy mortar is tightly packed and carefully maintained.
4. Hole: The general hole treatment method is to remove the loose concrete and weak slurry film around. How to repair the uneven surface of concrete external wall? Wash it with pressure water, and support the template with tray. When water is wet, its strength is higher than that of structure. Made of high-strength epoxy mortar, carefully layered, compacted and solidified.
5. Rotten roots: the outline of loose concrete and weak particles will always be a special afternoon after being cleaned and shaped. Grouting is tight.
6. Crispy and loose: shallow and loose, can be chiseled loose, loose and wet, and then use the infinite Zhi Zhi? Leveling and compacting the modified epoxy mortar. It is deeper and looser, and brittle and prominent particles can be chiseled out. How to repair the unevenness of the concrete external wall, you can use high-strength mortar with higher strength than the structural high-strength mortar to clean the mold, and strengthen the maintenance by strong compaction.
7. Cracks and interlayers: If it is not deep, loose concrete can be chiseled, and then washed with infinite Zhi Zhi? Dense packaging of polymer cement mortar. When it is deep, the loose parts and internal inclusions should be removed, the mold should be washed with pressurized water, the fine concrete should be compacted, or the surface should be closed before grouting.
8. Missing corners: You can remove smaller edges and corners from loose stones. How to repair the unevenness of concrete external wall? Brush with steel wire, rinse with water, fully moisten, and use infinite wisdom? Cleaning of polymer cement mortar. Larger edges and corners are removed. After cleaning and mold drawing, the mold is filled with high-strength non-shrinkage grouting and solidified.
9. Roof loosening: the mortar layer on the top of pine is cut, washed and fully wetted, and then filled with high-strength non-shrinkage grouting and maintained. ?
10. The surface is not smooth: polish the concrete surface with an angle grinder (gold millstone). ?
1 1. Displacement inclination of shear wall: displacement inclination does not affect the structural quality. How to repair the unevenness of concrete external wall only needs a small amount of local chisel and repair. Generally speaking, it is made of polymer cement mortar or fine stone concrete, without wit, and its strength grade is higher than the original concrete. Fix it.
12, concave-convex, convex: convex and convex do not affect the structural quality, and reduction method can be used. When the structural performance of the structure is affected, it should be handled after the relevant departments study the treatment scheme.
The above is some information about how to repair the unevenness of concrete external wall, I hope it will be useful to you.
