    Redwall Powder-superplasticizers

    Column:Product introduction Time:2021-07-22

     

    Product:Poly naphthalene sulfonate sodium salt (PNS)

    Benefits:

    -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.

    Performance

    -Very High strength                      

    -High early strength

    -Good workability

    -Low water-to-cement ratio, down to 0.3 and less

    -Good durability and sustainability

    Usage:  

    Redwall PNS is a major ingredient in different types of Superplasticizer 

    formulations 

    Dosage: 

    -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

    precautions:  

    -Eyes: direct contact may cause irritation

    -Skin: prolonged contact may cause irritation

    -Ingestion: May be harmful

    -DON’T TAKE INTERNALLY 

    -Wash thoroughly after handling
