Superplasticizer PC-250: High-Performance Concrete Admixture

Superplasticizer PC-250 is a high-range water-reducing admixture specifically designed to enhance the workability and performance of concrete mixes. This powerful, next-generation admixture significantly improves the flow and slump retention of concrete, allowing for easier placement and finishing, even with lower water-cement ratios. This results in stronger, more durable concrete with improved long-term performance.

Key Benefits:

• Increased Workability: PC-250 dramatically increases the slump of concrete mixes, making them significantly easier to pump, place, and consolidate. This reduces labor costs and improves overall efficiency on the job site.
• Reduced Water Content: Allows for significant reductions in water content without sacrificing workability. Lower water-cement ratios lead to higher strength, improved durability, and reduced shrinkage cracking.
• Improved Slump Retention: Maintains workability over extended periods, providing more time for placement and finishing, particularly beneficial in large pours or hot weather conditions.
• Enhanced Durability: By reducing the water-cement ratio, PC-250 contributes to increased resistance to freeze-thaw cycles, chloride penetration, and other forms of deterioration.
• Increased Strength: Higher strength concrete is achieved due to the optimized water-cement ratio, resulting in a more robust and longer-lasting structure.
• Cost-Effective: While initially a higher cost than some admixtures, the overall savings from reduced labor, cement, and potential future repairs make PC-250 a cost-effective solution in the long run.
• Ease of Use: PC-250 is easily added to the concrete mix during the mixing process. Detailed dosage recommendations are provided with each shipment.

Typical Applications:

• Ready-mix concrete
• Precast concrete elements
• High-performance concrete
• Self-consolidating concrete (SCC)
• Shotcrete applications

Specifications:

• Appearance: Dark brown liquid
• Specific Gravity: Approximately 1.15 - 1.20
• Chloride Content: Very low (check specific TDS for exact values)
• Dosage: Typical dosage ranges from 0.5% to 2.0% by weight of cement. Optimal dosage should be determined through laboratory testing, considering the specific mix design and desired properties.

Storage and Handling:

• Store in a cool, dry place, away from direct sunlight and freezing temperatures.
• Protect from contamination.
• Handle with care, avoiding spills and splashes.
• Refer to the Safety Data Sheet (SDS) for detailed safety information.
