Polycarboxylate Superplasticizer


Polycarboxylate Superplasticizer

Polycarboxylate Superplasticizer is used as a high range water reducing admixture in high performance concrete, high strength concrete, high volume fly ash/slag concrete, cement grouting, and dry mortar. These polymers are used as dispersants, especially for early strength concrete, to avoid particle segregation. They allow a water reduction up to 40% even with low dosage (.2-.3%) and have excellent durability. UMC currently offers two powder grades of Polycarboxylate superplasticizer; R-209 and SP-409.

R-209 is specialized for gypsum, cement grouting, mortar and other fields. R-209 enhances the fluidity and increases crack resistance of solidified cement. It is widely applied in non-shrinkage grouting, repair mortar, cement base floor grouting, water proofing grouting, and ceramics. It can be used directly or diluted with water. It is the best option for applications requiring rapid curing as it provides both early strength and ultimate high strength. R-209 is a green environmental product up to the standard of ISO14000.

SP-409 is mainly used in the field of concrete and has high performance slump retention. The index of performance of SP-409 is the same as the index of pumping agent. Due to uniform particle size, it can easily dissolve in water and be used with ready-mix and on-site concrete. It can easily meet the requirement of building plants in remote areas with simple usage by mixing product with water.
