Polycarboxylic Acid Water-Reducing Agent


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

  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 one hour and less than 10% in two hours.
  3. High compressive strengths. It can increase the compressive strengths of concrete by 50~110% in three days, 40~80% in twenty-eight days, and 30~60% in ninety days.
  4. Excellent workability. High ability against bleeding or segregation, low resistance, and easy pumping.
  5. Suitable bubble content, no bad influence on the concrete modulus of elasticity, and good freeze resistance.
  6. Less than 0.2% alkali content.
  7. Nontoxic, has no formaldehyde, and no pollution.
  8. Stable performance, no delamination, 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.

  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. Therefore, water content should be strictly controlled.
  4. Concrete cures should be paid attention to.


The polycarboxylic acid water-reducing agent is suitable for pumping or normal concrete engineering of C15~C60, particularly for engineering with high durability, fluidity, strong slump retention ability, and aesthetic appearance. In addition, this product is a good choice for high fluidity, self-compacting, and as-cast finish concrete.

Packing and Storage:

Liquid, package in a barrel, storage for one year in a dry and shady place, avoiding frost.
