Polycarboxylate superplasticizer (PCE) is a high-performance, water-reducing admixture for modern concrete applications. Utilizing advanced polymer technology, it offers superior slump retention and strength enhancement compared to traditional superplasticizers.
Performance Characteristics
--Water Reduction: 25-40% (vs. 15-25% for naphthalene-based)
--Slump Retention: Maintains workability for 2-4 hours
--Early Strength: 50-80% higher at 1 day vs. conventional SPs
--Compatibility: Works with all cement types (OPC, SCC, slag cement)
--Low Dosage: 0.1-0.3% by cement weight (1/3 of sulfonated melamine types)
Applications
1. Ready-Mix Concrete
Ideal for transit-mixed concrete requiring long workability
Reduces segregation in high-slump mixes (200-250mm)
2. Precast/Prestressed Concrete
Enables early demolding (12-16 hour cycle time)
Improves surface finish quality
3. Self-Consolidating Concrete (SCC)
Achieves 600-800mm flow without vibration
Maintains stability at low water/cement ratios (0.28-0.32)
4. High-Performance Concrete
Enables 100+ MPa compressive strength
Reduces autogenous shrinkage by 30-50%
