Concrete Surface Patching Mortar - Main Application
Primarily suited for surface damages on concrete structures such as hollows, honeycombs, cracks, spalling, and exposed reinforcement, to restore the good service performance of the concrete structure. It can also be used as a leveling mortar for carbon fiber reinforcement, high-performance masonry mortar, and as a protective leveling mortar for reinforcement with steel wire ropes in buildings or structures. This product, enriched with various polymer modifiers, glue powder, and crack-resistant fibers, boasts excellent workability, adhesion, impermeability, resistance to spalling, frost-thaw resistance, carbonation resistance, crack resistance, and corrosion inhibition for reinforcing steel, along with other properties.
Road Sand Patching Mortar Features
1Easier Construction: Offers good workability and ease of use. No vibration is required during construction; just add water on-site and mix.
2Early strength, :1Ultimate tensile strength up to20MpaMaximize engineering progress within the given deadlines.
3Excellent waterproofing properties: Strong resistance to seepage.1.7MpaWaterproof and resistant to hydrostatic pressureP16Requirements for concrete impermeability performance
4Excellent bonding performance: When using concrete surface treatment agents, the bonding strength with new and old concrete is greater than1.8MpaEnsures a tight bond between the concrete repair mortar and the repaired base to a great extent.
5Can be applied in winter: Polymer repair mortar allows environmental temperature of-5When above °C, outdoor construction is carried out for repairing the door facade, horizontal surface, and ceiling of concrete structures.
6High durability:50After one freeze-thaw cycle, there is no significant change in strength, soaked in engine oil.30Aftermath intensity enhanced.
Road Patching Mortar Application Method
1Base level requirements and treatment: The base surface should be smooth, rough, clean, oil-free, dust-free, and free of sanding, hollowing, and cracking. Prior to construction, it should be washed with high-pressure water and kept moist, but without standing water. Before bonding, a primer can be pre-applied.
2Material Proportioning: Powder to water ratio by weight100：13Measure and place. Actual amount used.90Pour the remaining water into the powder and mix thoroughly.10Water should be gradually poured in while stirring to avoid lumps, and the mixed paste should ensure that30Use within minutes.
3Construction: On the moist concrete subgrade surface, the area for applying patching mortar should not be too large in one go. It should be constructed in strips and blocks, with each block not exceeding a certain area.10When performing layered construction, the joint locations should be staggered.
4After the patching mortar is spread, it should be pressed and leveled in one go, and it is not advisable to repeat the pressing and leveling process. If bubbles are encountered, they should be pierced and pressed tightly, ensuring a dense surface. The thickness of the facing layer on the vertical or overhead surface should be greater than10mmConstruction should be carried out in layers.
