Product Features: Engineered for Excellence
The PC-826 superplasticizer is engineered to address critical challenges in concrete construction. Its core features include:
High Plasticity and Slump Retention
One of the standout characteristics of PC-826 is its ability to maintain high plasticity and slump retention. This means the concrete remains workable for extended periods, reducing the temporal loss of flowability during construction. This feature is particularly valuable in large-scale projects where prolonged workability is essential to ensure consistent quality and efficiency.
Exceptional Dispersion Ability
PC-826 exhibits high dispersion, enabling it to rapidly adsorb into cement particles. This property significantly reduces mixing time, enhancing productivity on construction sites. The improved dispersion also ensures a more uniform distribution of the superplasticizer, leading to better concrete homogeneity and structural integrity.
Enhanced Durability and Performance
The product enhances the compaction of the hardened slurry, improving the concrete's shrinkage and creep performance. By minimizing cracks and other structural weaknesses, PC-826 contributes to the long-term durability of concrete structures. This makes it ideal for applications where resistance to environmental stressors is critical.
Green and Environmentally Friendly
PC-826 is formulated without harmful substances, making it a green and environmentally friendly alternative to traditional superplasticizers. Its eco-conscious design aligns with global efforts to reduce the carbon footprint of construction materials, ensuring safety for both workers and the environment.
Technical Specifications: Precision in Every Detail
The PC-826 superplasticizer meets rigorous technical standards, as outlined in the following table:
| Order Number | Monitoring Project | Qualification |

- Various Portland Series Cement Concrete Systems
- Concrete Systems Requiring Long-Term Workability
Its adaptability makes it suitable for applications such as high-rise buildings, infrastructure projects, and specialized concrete formulations. The product's ability to maintain slump retention ensures that it performs exceptionally well in environments where prolonged workability is essential, such as in hot climates or large-scale pours.
Usage and Handling: Best Practices for Optimal Results
To achieve the best results, the following guidelines should be followed:
- Mixing Instructions: PC-826 can be mixed with water and added to concrete simultaneously. For optimal performance, it is recommended to mix it with water first before adding it to the concrete.
- Dosage Recommendations: The recommended dosage is 0.05–0.20% of the cementitious material. Adjustments should be made based on specific project requirements and raw material properties.
- Compatibility: PC-826 should be used in conjunction with water-reducing agents to maximize its effectiveness.
- Storage: Store in a ventilated, dry place with moisture-proof measures. Avoid direct sunlight and ensure timely use after opening to prevent degradation.
Packaging and Storage: Ensuring Quality and Safety
PC-826 is packaged in paper-plastic composite bags, with each bag containing 25 kg of the product. The shelf life is 12 months from the production date, and the product must be tested before use if it exceeds this period. Proper storage conditions are critical to maintaining the product's efficacy and safety.
