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. Co***red with other similar products, this product is better in its performance and performance/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 co***tibility, co***tibly with many cement types and mineral admixtures, particularly fit for high durability concrete and self co***cting 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 water-reducer. Co***tibility tests should be conducted beforehand when mixed with other auxiliaries.
3. Slump retention is sensitive to water, water content should be strictly controlled.
