Concrete Admixtures Polycarboxylate Superplasticizer PCE

Molecular main chain of polycarboxylate high performance water reducer is firmly adsorbed on surface of cement granule where can efficiently counteract hydration reaction and increase its plasticity. Branched chain surround cement granule having sterically hindered and electrostatic exclusion function which is different from conventional imparts excellent dispersing ability and effect of water reducing which make integrative characteristics of concrete improve greatly.

Principal performance
1. High water reduction: The water reduction rate of concrete can be high to 40%.
2. Good slump retention ability: Delaying time of transporting concrete and time of detention at construction site, guarantee concrete pumpability.
3. Good adhesion: Making concrete have excellent workability, Non-layer,without segregation and bleeding.
4. Good dispersion: High fluidity of concrete results in deposing and compacting easily for self-compacting concrete.
5. High strength gained rate: Greatly increasing early and after strength, reducing energy loss. Reduction of cracking, shrinkage and creep.
6. Wide adaptability: It is compatible with ordinary silicate cement, silicate cement, slag silicate cement and all kinds of blendings having excellent dispersibility and plasticity.
7. Good strength and durability: low lacuna rate, low alkali and chlorin-ion content. Enhancing concrete strength and durability
8. Environmental friendly products: No pollution during production.
