PC-306 is a powder polycarboxylate superplasticizer produced based on polycarboxylate technology. By optimizing molecular configuration and synthesis process, it has a new generation of superplasticizer products with high water reduction rate and early strength. For Ultra-High Performance Concrete with low water-binder ratio and high strength requirements.
Complies with The ASTM C 494 Norm
ASTM C 494, Type A and F
Advantages:
·High Water Reduction Rate: With a low dosage, it possesses a high water reduction effect, suitable for low water-cement ratio applications.
·High Dispersion: It has excellent dispersibility, and can be quickly absorbed, giving the fresh pastes excellent workability and constructability.
·High Compatibility: It has excellent adaptability with various cement-based systems.
High Early and Later-age strength: It exhibits excellent early-stage and later-stage strength.
·High Durability: It enhances the compactness of the hardened pastes, improves shrinkage and creep performance, reduces cracks, and improves durability.
·Eco Friendly: Does not contain harmful substances, safe and environmentally friendly.

Application:
PC-306 has excellent dispersibility and is particularly suitable for various high-grade cement systems. Such as in:
·Ultra-High Performance Concrete (UHPC)
·Other high-strength, high-performance concrete.
Uses:
1.Before use, PC-306 needs to be mixed evenly with other dry powder components. The construction mixing and application should be carried out according to the specific requirements of the different fields of application.
2.The recommended dosage of PC-306 is between 0.10% and 0.50% of the binders. The exact amount to be used should be determined by trial mixing based on the application system and variations in the dry-mix components.
Packaging:
1.The shelf life is 12 months from the date of production. If the shelf life has expired, testing and verification must be carried out before use.
2.Store in a well-ventilated and dry place. Measures should be taken to prevent moisture. Avoiding direct sunlight.After opening, it should be used promptly. If not all of it is used, it should be sealed promptly to prevent it from absorbing moisture and becoming spoiled.
