  • PCL Polycarboxylate Superplasticizer Concrete AdmixturePCL polycarboxylate superplasticizer concrete admixture features good stability especially at low temperature. Besides, the liquid concentration of our product can be diluted from 50% to 10% and then you can directly use the diluted product as pumping admixture of mixing plant.
  • FDN Naphthalene Sulfonate Formaldehyde Condensate Concrete AdmixtureCompared with UNF-5 type, FDN naphthalene sulfonate formaldehyde condensate concrete admixture has higher water reducing rate and fewer concrete slump loss, which can efficiently increase the concrete fluidity, reduce bleeding and segregation and then improve the workability of concrete.
