Releasing polycarboxylate sodium salt (PCE), Slow-release Comb-polycarboxylate
-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.
Properties Unit Specification
Solids content % w/w 38-40
pH of 10% solution 5.0-6.0
Properties Unit Typical
General appearance colorless-light yellow
Ionic nature anionic
Chlorides (as Cl-) ppm <25
Solubility dilutes rapidly in hard or soft water
-Mixing with normal polycarboxylate superplasticizer at any ratio.
-Control the slump loss induced by weather conditions.
-Control the slump loss stemming from the minerals, e.g., fly ash, mud/soil, etc.
- By mixing with JBJ, Polycarboxylate superplasticizers provide workability
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
-When added at normal dosage, it will not significantly affect the concrete’s
The retention of JBJ to the normal polycarboxylate superplasticizer depends
on the specific designing of concrete workability, 20%-60% in whole mixture
-supplied in 225kg drums, in 1000kg totes, or in bulk
-storage at room temperature is recommended
-Recommended storage period: not exceeding 6 months
-Mildly acidic material
