China Low Dosage Tpeg Series Concrete Superplasticizer Polycarboxylate Ether

Low Dosage Tpeg Series concrete superplasticizer Polycarboxylate Ether (0.2%-0.5%)
polycarboxylate
polycarboxylate ether
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 or6:4,accurate ratio is according to you concrete material.

advantages:
polycarboxylate ether

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
