What is concrete pavement patching agent? Peeling of cement pavement is a very typical cement pavement disease. It not only harms the internal structure of the cement pavement, shortens the service life of the cement pavement, but also poses a great safety hazard to the driving of vehicles. But what about peeling of cement pavement? What about repairing

1. Basic requirements
Dosage;
When the repair thickness is 3mm, the dosage is approximately 5.1kg per square meter. The water should be non-polluted water (drinkable for livestock). The construction thickness should be above 3mm.
Construction conditions;
The temperature must be above 5 degrees, and construction cannot be done in rain or snow.
Construction personnel must have certain experience in cement concrete construction.
Construction tools;
Mortar mixer or manual mixing tool (modified hand drill), High-pressure water washing equipment, milling machine, bottom cleaning tools, sponge or mop (for absorbing excess water), two or more mixing barrels, several trowels, etc.
2. Bottom surface treatment
Cleaning;
First remove the loose parts such as bulging, peeling, cracks and other parts, and roughen the parts below 3mm, parts that are too flat and parts with grease, or use a milling machine to remove the surface. Mill to reveal solid base.
Cleaning;
Clean up the floating soil and other debris on the bottom and flush it with high-pressure water Clean, when flushing, the mud should be flushed out of the working surface and prevent backflow.
Moisturizing;
After washing with water, the water should be kept on the working surface for a while Time, fully moisten the working surface until no more water seeps.
3. Material preparation
Pour the road and bridge quick repair materials into the container, and add the amount of water. The effect is 15%, but the amount of water added can be adjusted according to different repair parts and different requirements for fluidity, and the mixture must be fully stirred evenly.
4. Construction method
The surface to be repaired should be fully moistened, and the surface should be moist but not clear. When the water is ready, pour the mixed repair material onto the work surface and spread it evenly with a trowel.
5. Cement pavement maintenance
Used to repair and reinforce concrete surface defects and uneven surfaces Smoothing;
Thickening of protective layer, repair of old concrete surface, etc.;
Improve the durability of cement roads, extend the service life of concrete, and prevent the erosion of concrete by acids, alkalis, and salts using water as a carrier;
