Polycarboxylic Acid Water-Reducing Agent

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


1. Low dosage and high range of water reduction efficiency. Water reduction efficiency of this superplasticizer can be up to 45%;

2. High slump-retaining ability. This concrete superplasticizer can less 5% slump loss in 1h, and less 10% in 2h.

3. High compressive strengths. Polycarboxylic acid water-reducing agent 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. High compatibility, compatibly with many cement types and mineral admixtures, particularly fit for high durability and self compacting concrete.

Usage methods:

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 superplasticizer. Compatibility tests should be conducted beforehand when mixed with other auxiliaries.

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

4. Concrete cure of Polycarboxylic acid water-reducing agent should be paid attention to.

Scope of applications:

Polycarboxylic acid water-reducing agent is suitable for pumping or normal 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 water reducing, this superplasticizer is a better choice.

Package and Storage:

Polycarboxylic acid water-reducing agent is liquid status, package in barrel, storage for one year in dry and shady place, avoiding frost.
