Redwall Powder-superplasticizers
Column:Product introduction Time:2019-11-07

Product:Poly naphthalene sulfonate sodium salt (PNS)


-Improves the flow properties of the concrete mix by dispersing the particles and 

 breaking up agglomeration by electrostatic repulsion. 

-Improves the rheological and mechanical properties of concrete such as 

 workability, compressive and flexural strengths, modulus of elasticity.

Redwall PNS is a major ingredient in different types of Superplasticizer 



-Normal dosage rate: 200-1000g per 100kg of cement

-Other dosages may be required depending on specific conditions

-Redwall PNS fluidified concrete remains workable for approximately 90 minutes 

 at 20oC 

-Duration of workability also depends on:

-type of cement-nature of aggregates 

-method of mixing-method of transportation 

-ambient temperature

-When added at normal dosages, it will not significantly affect the concrete’s 

 hydration heat

Packaging, Storage   

-supplied in 1000kg and 1250kg bages

and Handling:  

-storage at room temperature is recommended

Safety and Handling   

-Mildly alkaline material


-Eyes: direct contact may cause irritation

-Skin: prolonged contact may cause irritation

-Ingestion: May be harmful


-Wash thoroughly after handling
