IZOZENĀ® IZONEP 503 PK
IZOZENĀ® IZONEP 503 PK is a high-performance plasticising and slump-retaining concrete admixture. It is a dual-action liquid superplasticiser that delivers excellent slump retention for prolonged periods, while also improving workability and strength.
Key Applications
This admixture can be used as a superplasticiser and as a water reducer in concrete.
As a Superplasticiser:
Improves workability.
Concrete is easier to place and needs less vibration.
Best for slender components with dense reinforcement.
Enhances cohesion, reduces segregation, and allows more placement time.
As a Water Reducer:
Provides significant water reduction.
Enhances final strength.
