Redwall JSMs polycarboxylate superplasticizer

Column:Product introduction Time:2021-07-22

 

Product:Poly carboxylate sodium salt (PCE), Star structure polycarboxylate   

Benefits:

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

 and breaking up agglomeration by electrostatic repulsion. 

-It is a potential high-range. Mid-range and low-range water reducer for the 

 ready-mix and precast markets.

-Compared to many PCEs on the market, it is less sensitive to the cement with 

 high water reducing ability. While providing good retention.

-Improves the rheological and mechanical properties of concrete such as 

 workability, compressive and flexural strengths, modulus of elasticity.

Solubility                                                   dilutes rapidly in hard or soft water


Application:

-Intended principally for precast applications where high water reduction 

 and high early strength as required.

-High and ultra-high performance concrete-Self-compacting Concrete

-Pumped concrete- Pervious

-Marine concrete-Gunite concrete

-Architectural concrete-Blended cement concrete

-Lightweight concrete-High and ultra-high performance concrete


Performance:

-Very High strength       

-High early strength

-Good workability         

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

-Reduced cement and reduced carbon footprint

-Good durability and sustainability


Usage:       

All products from the REDWALL JSM family are based on the same 

polycarboxylate ether polymers. 

-is the original product from the series

-does not contant any antifoaming agent.


Dosage:  

-Normal dosage rate: 40-650ml per 100kg of cement

-Other dosages may be required depending on specific conditions

-Redwall PCEs 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 225kg drums, in 1000kg totes, or in bulk 


and Handling: 

-storage at room temperature is recommended

-Recommended storage period: not exceeding 6 months

-Mildly acidic material            

-Manipulate safely

-DON’T TAKE INTERNALLY
