- Mass Concrete: Reduces heat of hydration, preventing thermal cracking in large structures like dams and foundations.
- Concrete with Fly Ash or Slag: Enhances the performance of eco-friendly mixes by improving flowability and reducing cement content.
- Special Concretes: Suitable for precast elements, self-consolidating concrete, and other specialized applications.
Usage Instructions and Precautions
To maximize the benefits of the PC-733, follow these guidelines:
- Measurement and Mixing: The product can be diluted with water before adding to concrete or mixed directly into the batch. The latter method is recommended for optimal results.
- Dosage: The recommended dosage ranges from 0.10% to 0.40% of the cementitious material. Adjust based on concrete design requirements and material conditions.
- Homogeneity: When using dry powder, ensure thorough mixing to maintain uniformity. Avoid clumping by adding water gradually.
Packaging and Storage
The PC-733 is packaged in paper-plastic composite bags at 25 kg per bag. For optimal storage:
- Keep in a dry, well-ventilated area to prevent moisture absorption.
- Avoid direct sunlight and ensure the packaging is sealed after use.
- Shelf life is 12 months from the production date. If stored beyond this period, retesting is recommended before use.
