- Special Concrete: Tailored for unique applications such as marine structures or extreme weather environments.
Usage Guidelines
To maximize the benefits of PC-733, follow these recommended procedures:
- Measurement and Mixing: Dissolve the powder in water before adding it to the concrete mix. For optimal results, mix the powder with water first, then add to the concrete (Product Manual).
- Dosage: The recommended dosage is 0.10–0.40% of the cementitious material. Adjust based on concrete design requirements and material properties.
- Homogeneity: Ensure even mixing of the powder to avoid clumping. For dry premixes, thorough blending is critical before adding water.
Packaging and Storage
PC-733 is packaged in paper-plastic composite bags at 25 kg per bag. To maintain quality:
- Store in a ventilated, dry area away from direct sunlight.
- Protect from moisture to prevent degradation.
- Use within 12 months of production. If the shelf life has expired, test the product before use.
- Seal the bag immediately after opening to avoid moisture absorption.
