Compared with other similar products, Polycarboxylic Acid Water-Reducing Agent is better in its performance and performance/cost ratio. Properties of Polycarboxylic Acid Water-Reducing Agent: 1.Polycarboxylic Acid Water-Reducing Agent has Low dosage and high range of water reduction efficiency. Its water reduction efficiency can be up to 45%; 2.Polycarboxylic Acid Water-Reducing Agent has High slump-retaining ability. Slump loss of the concrete is less than 5% in 1h, and less than 10% in 2h. 3.Polycarboxylic Acid Water-Reducing Agent has 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.Polycarboxylic Acid Water-Reducing Agent has Excellent workability. High ability against bleeding or segregation, low resistance and easy for pumping 5.Polycarboxylic Acid Water-Reducing Agent has Suitable bubble content, no bad influence on concrete modulus of elasticity, good freeze resistance; 6.Polycarboxylic Acid Water-Reducing Agent has Less than 0.2% alkali content, 7.Polycarboxylic Acid Water-Reducing Agent has Nontoxic, no formaldehyde and no pollution; 8.Polycarboxylic Acid Water-Reducing Agent has Stable performance, no delamination and no sedimentation for long storage period, no crystallization in low temperature. 9.Polycarboxylic Acid Water-Reducing Agent has High compatibility, compatibly with many cement types and mineral admixtures, particularly fit for high durability concrete and self compacting concrete. Specification of Polycarboxylic Acid Water-Reducing Agent: items index Appearance light brown liquid Density (20℃) g/ml 1.09±0.02 Solid content % 22±2 Cement paste fluidity (cement base) (mm) 250（W/C=0.29） pH 6-8 Chloride % ≤ 0.02 pH value(1％ water solution) 1.5~2.0 Alkali (Na2O+0.658K2O)(%) ≤ 0.2 Usage methods of Polycarboxylic Acid Water-Reducing Agent : 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, water content should be strictly controlled. 4. Concrete cure should be paid attention to. Scope of applications of Polycarboxylic Acid Water-Reducing Agent : Polycarboxylic Acid Water-Reducing Agent is suitable for pumping or normal concrete 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 as cast finish concrete, this product is a good choice. Package and Storage of Polycarboxylic Acid Water-Reducing Agent: Liquid, package in barrel, storage for one year in dry and shady place, avoiding frost.
