Superplasticizer introduction:

Polycarboxylic acid water-reducing agent is a kind of concrete superplasticizer with good comprehensive properties and good perspective. Superplasticizer is a composite admixture of polycarboxylate copolymers and other auxiliaries. Compared with other similar products, Superplasticizer is better in its performance and performance/cost ratio.

Superplasticizer Properties:

1. Polycarboxylic Acid Water-Reducing Agent (Superplasticizer)  has low dosage and high range of water reduction efficiency. Its water reduction efficiency can be up to 45%;

2. Polycarboxylic Acid Water-Reducing Agent (Superplasticizer)  has high slump-retaining ability. Slump loss of the concrete is less than 5% in 1h, and less than 10% in 2h.

3. Polycarboxylic Acid Water-Reducing Agent (Superplasticizer) has high compressive strengths. It can increase the compressive strengths of concrete by 50-110% in 3 days, 40-80% in 28 days, 30-60% in 90 days.

4. Excellent workability. High ability against bleeding or segregation, low resistance and easy for pumping;

5. Suitable bubble content, no bad influence on concrete modulus of elasticity, good freeze resistance.

6. Less than 0.2% alkali content.

7. Nontoxic, no formaldehyde and no pollution.

8. Stable performance, no delamination and no sedimentation for long storage period, no crystallization in low temperature.

9. Polycarboxylic Acid Water-Reducing Agent (Superplasticizer) has high compatibility, compatibly with many cement types and mineral admixtures, particularly fit for high durability concrete and self compacting concrete.

Superplasticizer Specification:

items index
Appearance light brown liquid
Density (20℃) g/ml 1.09±0.02
Solid content % 22±2
Cement paste fluidity (cement base) (mm) 250（W/C=0.29）

Usage:

1. The dosage is 0.4-2.0% of the cementitious materials by weight, normally 0.4-1.2%. Do concrete mixture tests beforehand. 　

 2. No mixture with naphthalene-base water-reducer. Compatibility tests should be conducted beforehand when mixed with other auxiliaries. 　　

 3. Slump retention is sensitive to water,water content should be strictly controlled. 　　

4. Concrete cure should be paid attention to.

Scope of applications:

Polycarboxylic Acid Water-Reducing Agent (Superplasticizer) is suitable for pumping or normal concrete engineering of C15-C60, particularly for engineering with high durability, excellent fluidity, strong slump retention ability and excellent aesthetic appearance.For high fluidity, self compacting and as cast finish concrete, this product is a good choice.

Package and Storage:

Acidity, Avoid contact with eye and skin, once contacted, flush with water.
