Huaxuan High-tech® PC-306
Polycarboxylate Superplasticizer Powder (For Ultra-High Performance Concrete /UHPC)
![]() | Huaxuan High-tech® PC-306 is a powder polycarboxylate superplasticizer produced based on polycarboxylate technology. By optimizing molecular configuration and synthesis process, it is new generation of superplasticizer with high water reducing rate and early strength. For Ultra-High Performance Concrete with low water-binder ratio and high strength requirements.
PC-306 complies with The ASTM C 494 Norm |
High water reduction rate At low content, it has a high water reduction efficiency to adapt to low water-binder ratio. | ![]() |
High dispersion It has excellent dispersion ability and can be adsorbed quickly, giving the concrete system excellent workability and constructability. | |
Early strength and high strength Has excellent early strength and enhancement effect. | |
High durability Enhance the compactness of the hardened concrete paste, improve the shrinkage and creep properties to improve the durability of concrete. |
