Polycarboxylate Superplasticizer (PCE)
High Water Reduction: Up to 40% water reduction, lowers water-cement ratio significantly.
Excellent Slump Retention: Maintains high fluidity for 2–3 hours, ideal for long-distance pumping.
High Early & Final Strength: Accelerates hydration, boosts early strength (1d/3d) and long-term durability.
Wide Compatibility: Works with all cement types (OPC, slag, fly ash) and other admixtures.
Low Dosage & Eco-Friendly: Dosage 0.6%–1.2% by cement weight; low alkali/chloride, non-toxic.
Improved Durability: Reduces shrinkage/cracking, enhances impermeability and freeze-thaw resistance.
Polycarboxylate superplasticizer (PCE) is a third-generation high-performance water reducer with a comb-shaped copolymer structure. It disperses cement particles effectively, producing high-flow, high-strength, and durable concrete with minimal water content.
