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)
|Item Name||polycarboxylate superplasticizer||Model||PCE|
|Appearance||White or yellowish liquid||Application||superplasticizer|
|pH value||5-8(can be adjusted)||Certification||SGS|
|Solid content||40-50%||Function||water reducing agent|
|Specific gravity||1.08+-0.03||Price||USD 870~960|
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.

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

b,performance for high slump retention polycarboxylate
(50% mother liquid) tested by Shanlv P.O.42.5 ordinary portland cement,with the dosage of 0.32%
87g water+0.96g CL-50+300g cement
|Time (min)||slump variation retention (mm)||state|
weak of other agent
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
