Redwall JBJ

Product

Releasing polycarboxylate sodium salt (PCE), Slow-release Comb-polycarboxylate 

Benefits

-Improves the flow properties of the concrete by polycarboxylate superplasticizers 

 with mixingREDWALL JBJ

-Provides extended slump retention for ready-mix applications.

-Engineers for hot weather concrete, long haul or to minimize the need for slump 

 adjustment at the jobsite.

-Promotes complexity at the jobsite: time consumption, QC time and risk of over 

 dosage of superplasticizer or of adding water.

-Control the slump loss stemming from the minerals, e.g., fly ash, mud/soil, etc.


Performance characteristics

- By mixing with JBJ, Polycarboxylate superplasticizers provide workability 

  retention 

  for maximum 120 min as designed.

- Duration of workability also depends on:



-Dosage rate when used as is or with a blend of admixtures:

-Type and brand of cement   

-Nature of the aggregates 

-Method of mixing        

-Method of transportation

-Ambient temperature 

-When added at normal dosage, it will not significantly affect the concretes 

  hydration heat.


Mixing ratio:     

The retention of JBJ to the normal polycarboxylate superplasticizer depends 

on the specific designing of concrete workability, 20%-60% in whole mixture

is recommended.
