Compared to traditional superplasticizer, poly naphthalene/melamine sulfonate formaldehyde condensate,
- Extends slump life
- Reduces the dosage of superplasticizer
- Keeps the water/binder ratio to be a minimum
- Promotes high early strength
- Increases flowability
- Promotes workability
- Increases cohesiveness and segregation resistance
- Promotes pumpability
- Reduces shrinkage and cracks
- Promotes air stability
- Reduces bleeding at high slumps
Name
Specification
Naphthalene water reducers
1.Big slump loss
2.Hard to avoid segregation when dosage is slightly higher
3.Certain pollution to the environment as formaldehyde or benzene
Melamine water reducers
1.Air entraining performance is bad
2.Use cost is comparatively high
3.No highlight in its features
Lignosulfonate water reducers
1.Low water reduction
2.The performance is common
3.It's from 1930s, and is coming to be eliminated products. Still used today only for being eco-friendly and people's habit
4.Use cost is comparatively high
