Polycarboxylic Acid Water-Reducing Agent

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, particularly fit for high durability concrete and self compacting concrete.
