Superplasticizer PC-200: High-Performance Concrete Admixture

PC-200 is a high-performance, polycarboxylate-based superplasticizer designed to significantly improve the workability of concrete mixes while maintaining or even enhancing their compressive strength. It's ideal for a wide range of applications requiring high-strength, durable, and easily placed concrete.

Key Features & Benefits:

• Exceptional Water Reduction: PC-200 allows for significant reductions in water content (up to 30%, depending on cement type and mix design) without compromising slump or workability. This leads to:
  • Increased Strength: Higher cement-to-water ratios result in stronger, more durable concrete.
  • Improved Durability: Reduced porosity minimizes permeability, enhancing resistance to freeze-thaw cycles, chloride penetration, and other forms of degradation.
  • Cost Savings: Less cement can be used while achieving the desired strength, reducing material costs.
  • Enhanced Workability: Provides extended slump retention time, facilitating easier placement, consolidation, and finishing. This is particularly beneficial for complex structures and challenging pouring conditions.
• Extended Slump Retention: PC-200 provides excellent slump retention, giving contractors more time to work with the concrete before it begins to lose its workability. This reduces the need for re-mixing or adding additional water, further improving the final concrete quality.
• Compatibility: PC-200 is compatible with most types of cement, including Portland cement, blended cements, and high-performance cements. However, it is recommended to conduct compatibility testing for specific cement types and mix designs before large-scale implementation.
• Ease of Use: PC-200 is easily dispersed in water and readily mixes into concrete batches. Specific dosage recommendations should be determined through laboratory testing and tailored to the specific project requirements.
• Environmental Considerations: While PC-200 contributes to stronger and more durable concrete, reducing the overall amount of cement needed, its environmental impact should be assessed as part of the broader project sustainability plan.

Applications:

PC-200 is suitable for a wide variety of concrete applications, including:

• High-strength concrete structures
• Precast concrete elements
• Ready-mix concrete
• Self-consolidating concrete (SCC)
• Shotcrete applications
• Pumping concrete

Typical Dosage:

The optimal dosage of PC-200 varies depending on the cement type, mix design, desired slump, and other project-specific factors. It is crucial to conduct laboratory trials to determine the appropriate dosage for each specific application. A typical range is 0.5% to 2.0% by weight of cement.
