Polycarboxylate Superplasticizer (PCE)

Performance Advantages
​Remarkable Viscosity Reduction
Reduces plastic viscosity of concrete by ​20-30%, shortens cement paste drainage time (e.g., ​T200 and ​Marsh time reduced by 15-25%), and enhances pumping efficiency4.
In ​C60 high-strength concrete, achieves ​**≥95% slump retention rate** and ​**≤15% 1-hour fluidity loss**.
​Broad Adaptability
Compatible with ​manufactured sand, ​high-clay aggregates (clay content ≤3%), and low-quality admixtures (e.g., ​Grade II fly ash), effectively mitigating segregation and bleeding.
Stable performance across ​5-35°C environments; no crystallization in low-temperature storage and excellent viscosity stability during high-temperature construction1.
​Strength & Durability
Eliminates bleeding and segregation; ​alkali content ≤0.2%, complying with green building standards. Suitable for ​nuclear power plants, ​high-speed railways, and other durability-critical projects.
​Application Scenarios
​Specialized Concrete
​Self-compacting concrete, ​steel fiber-reinforced concrete, ​architectural fair-faced concrete, and ​wind turbine tower concrete.
​Complex Aggregate Conditions
​Manufactured sand concrete and mixes with ​high-clay aggregates (clay content ≤3%)
​Infrastructure Projects
Long-distance pumping for ​super high-rise buildings, ​large-span bridges, ​hydropower facilities, and ​nuclear power plants.
