Product Overview
Our Polycarboxylate Superplasticizer (PCE) is a state-of-the-art high-performance concrete admixture based on polycarboxylate ether copolymers. It delivers outstanding water reduction, exceptional slump retention, and significant improvements in concrete strength and durability. This product is the preferred choice for producing high-strength, self-compacting, and high-durability concrete.

Key Advantages
- Ultra-High Water Reduction: Achieves 25%–45% water reduction, significantly lowering the water-cement ratio while maintaining excellent workability.
- Superior Slump Retention: Slump loss is less than 5% in 1 hour and less than 10% in 2 hours — ideal for long-distance transport and hot-weather concreting.
- Exceptional Strength Gain: Increases compressive strength by 50%–140% at 3 days and 40%–80% at 28 days compared to reference concrete.
- Broad Cement Compatibility: Works well with various types of cement and supplementary cementitious materials (fly ash, slag, silica fume).
- Low Alkali & Chloride: Alkali content ≤0.2% and chloride ≤0.02% effectively prevent alkali-aggregate reaction and steel corrosion.
- Eco-Friendly: 100% formaldehyde-free, low VOC, and safe for both production workers and end-users.
- Cost-Effective: Saves 15%–25% cement at the same strength grade, significantly reducing overall mix cost.
Recommended Dosage
- Liquid form: 0.4% – 1.2% by weight of cementitious materials
- Powder form: 0.15% – 0.4% by weight of cementitious materials
Note: Optimal dosage should be determined through trial mixes based on specific project requirements and local materials.
Typical Applications
- High-strength and ultra-high-strength concrete (C50 – C100+)
- Self-compacting concrete (SCC)
- High-fluidity pumping concrete
- Mass concrete foundations and piers
- Precast and prestressed concrete elements
- Bridge decks, high-rise buildings, and marine structures
Packaging & Storage
- Liquid: 200kg drums, 1,000kg IBC totes, or 20,000kg tanker trucks
- Powder: 25kg multi-layer kraft paper bags with PE liner, or 500kg/1,000kg bulk bags
- Shelf Life: 12 months when stored in original sealed containers at 5°C – 35°C
