Airport Concrete Pavement Full-Slab Rapid Replacement with Quick-Drying Cement

Zhongda Hengjian Airport Pavement Pothole Rapid Repair Material is a high-tech product developed by Zhongda Hengjian in collaboration with national research institutions specifically for the rapid repair of airport concrete pavements. This product professionally treats surface defects in airport system cement pavements such as potholes, cracks, edge spalling, and broken corners. After repair, the color is aesthetically pleasing, the system is highly stable, and its waterproof and frost-resistant qualities are renowned in the industry.

Airport Pavement Pothole Rapid Repair Material is formulated using high-strength washed and dried sand as aggregate, special cement as a binder, and supplemented with high fluidity, micro-expansion, and anti-segregation agents. During construction, a certain amount of water is added, and after thorough mixing, it is ready for use. This material features excellent fluidity, no shrinkage, early high strength, strong impact resistance, high bonding strength, self-compacting properties, and strong weather resistance. The product's comprehensive performance is superior, meeting the construction needs of various airports, making it an ideal material for emergency repairs and rapid maintenance of airport runways, aprons, and support areas. For construction parties, it offers advantages such as reliable quality, cost reduction, shortened construction periods, and ease of use.

Core Advantages:
1. High Bonding Strength: Up to 4 times that of the original concrete, ensuring no hollowing or cracking after repair;
2. High Strength: Final strength can reach above C65;
3. High Toughness: Impact resistance is more than 20 times that of ordinary concrete;
4. Frost Resistance: The core technical material has extremely low water absorption and can withstand low-temperature freeze-thaw cycles below -40°C without hollowing or peeling;
5. Resistance to Salt Corrosion: Particularly resistant to corrosion from deicing agents.
6. Consistent Thermal Expansion and Contraction Coefficient: Ensures synchronous displacement with the original concrete during thermal cycles, preventing weak bonding or peeling due to inconsistent coefficients.
7. Fast Curing: Only 2 hours of curing required after construction before the pavement is ready for traffic.
