- Special Concrete: Suitable for specialized applications such as precast and ready-mix concrete.
Usage Instructions
To achieve optimal results, follow these guidelines for using PC-733:
- Measurement and Mixing: The product can be measured and mixed with water before adding to concrete, or added after mixing. The latter method is recommended for better performance.
- Dosage: The recommended dosage is 0.10–0.40% of the cementitious material. Adjust based on specific project requirements and material conditions.
- Homogeneity: Ensure even mixing of the powder to maintain consistency. Avoid pre-mixing in dry form without proper blending.
Packaging and Storage
PC-733 is packaged in paper-plastic composite bags with a standard weight of 25 kg per bag. The product has a shelf life of 12 months from the production date. For storage:
- Keep in a ventilated, dry area to prevent moisture absorption.
- Avoid direct sunlight and ensure moisture-proof treatment.
- Seal the package immediately after use to maintain quality.
