Polycarboxylate Super plasticizers Technology

1. Polycarboxylic acid water reducing agent is a kind of superplasticizer emerged in the early 80' s. It is mainly used in cement concrete. In chemistry, Poly-carboxylate-based is an organic and polymeric electrolyte. It belongs to a polymer surfactant. Therefore, it can also be applied in other paste materials such as gypsum products and ceramic products to reduce water content.

2.Poly-carboxylate is a weak electrolyte. It can only be fully dissolved in an alkaline solution .It can compound with cations in cement/water system to control the cement hydration process and thus to reduce the slump loss of the concrete. Poly-carboxylate achieves its water reducing effect through the yield of electrostatic repulsion and steric hindrance when it is absorbed to the cement particles. Hence, Poly-carboxylate is the most effective superplasticizer for cement concrete.

3.Poly-carboxylate is a raw material for superplasticizer. It is recommended that applicants should determine the Poly-carboxylate dosage in their own formulation according to their trial runs.

Polycarboxylate Superplasticizer Application:

1.Widly used in high strength concrete for railway, haven, traffic, bridge and electric power.

2.It is excellent superplasticizer in premix of construction and cast-in-place concrete.

3.It is especially suitable for the preparation of high strength, high durability self-compacting, steel fiber and self-leveling concrete.

Polycarboxylate Superplasticizer Advantage:

• When the W/C ratio is fixed, adding superplasticizer can improve the fludity and workability of the mixture.
• And when do not change the ratio of the raw materials(except water) and slump retention, it can reduce water consumption, at the same time improve the concrete strength(psi).
• When the ratio of the raw materials(except cement) and strength has no change, the concrete superplasticizer can reduce cement dosage even by 25-30%.
