Performance Features
● Low Heat of Hydration:
Releases less heat during hydration, effectively reducing cracks caused by temperature stress in large volume concrete.
● Slight Expansion
Produces moderate volume expansion during hardening, compensating for concrete drying shrinkage and cooling shrinkage, improving concrete density and crack resistance.
● Reasonable Strength Development:
Moderate early strength with continuous strength growth later, meeting the strength requirements of engineering structures.
● Good Durability:
Has good impermeability and frost resistance, enhancing the service life of concrete structures.
Application Scenarios
● Large Volume Concrete Projects:
Such as dams, large foundations, bridge piers, etc., using its low heat characteristics to reduce temperature cracks.
● Waterproof Projects:
Improves concrete density with slight expansion, suitable for waterproof areas like basements and pools.
● Repair Projects:
Can be used for repairing concrete structures, reducing shrinkage differences between repair areas and original structures.
