Polycarboxylate Superplasticizer, also call Polycarboxylic Acid Superplasticizer. As a high-performance water-reducing agent of powdery polycarboxylic acid, PS690 is recommended to be used in cement-based material system. With excellent water-reducing rate and plastic retention, it can significantly improve material fluidity and endue materials with excellent construction property and mechanical strength.
Application
Polycarboxylate Superplasticizer has good adaptability in various cement-based material systems and is widely used in dry mortar and concrete systems, such as self-leveling mortar, grouting material, grouting agent and concrete of different strength levels.
