Usage Instructions and Precautions
To achieve optimal results, PC-733 should be used according to the following guidelines:
- Measurement and Mixing: The product can be mixed with water before adding it to the concrete or directly added to the mix. The latter method is recommended for better dispersion.
- Dosage: The recommended dosage ranges from 0.10% to 0.40% of the cementitious material. Adjustments should be made based on specific project requirements and material conditions.
- Homogeneity: When using dry powder, ensure thorough mixing to maintain uniformity. After adding water, the mixture should be integrated into the concrete promptly.
Packaging and Storage
PC-733 is packaged in paper-plastic composite bags with a standard weight of 25 kg per bag. For optimal storage conditions:
- Store in a dry, well-ventilated area away from direct sunlight.
- Implement moisture-proof measures to prevent degradation.
- Use the product within 12 months of production. If the shelf life has expired, test the product before use.
- Seal the container111 immediately after opening to prevent moisture absorption.
