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

Properties:
1. Low dosage and high range of water reduction efficiency. Its water reduction efficiency can be up to 45%.

2. High slump-retaining ability. Slump loss of the concrete is less than 5% in 1h, and less than 10% in 2h.

3. 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. High compatibility, compatibly with many cement types and mineral admixtures
