Calcium Lignosulfonate

Calcium Lignosulfonate

Calcium lignosulfonate, commonly known as wood calcium, comes from the waste liquid of wood pulp produced by sulfite, which should be treated by off sugar processing, and concentration or spray drying. It can be applicable to concrete project for water reducing agent and retarding agent, which can improve both workability and quality of project. Also, it can be used as flotation agent, slag binder, pesticide filling agent and emulsifier.

Our calcium lignosulfonate helps concrete improve good workability and good concrete fluidity with high water reducing rate. Besides, it can increase density of concrete to improve concrete impermeability, frost resistance and durability with no erosion to steel bars. Our product can provide retarding function used alone or with naphthalene-based or amino-based superplasticizer.

  • 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.
