polycarboxylate
cement additives
Two types of liquid polycarboxylate super plasticizer
a. Polycarboxylate superplasticizer water reducing admixture (CL-WR)
b. Slow release polycarboxylate superplasticizer slump retention water reducing agent (CL-SL)
note:
1,CL-WR can be used separatly.
2,CL-SL can not be used separatly,ratio for water reducing type and slump retention type is usually 7:3 or 6:4,accurate ratio is according to you concrete material.

advantages:
cement additives
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

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 |
| 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 |
