Calcium Lignosulfonate

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

Our calcium lignosulfonatehelps concrete improve good workability and good concrete fluidity with highwater reducing rate. Besides, it can increase density of concrete to improveconcrete impermeability, frost resistance and durability with no erosion tosteel bars. Our product can provide retarding function used alone or withnaphthalene-based or amino-based superplasticizer.
