PCE Water Reducing Admixtures Polycarboxylate Superplasticizer Liquid 50%

At present, high-performance water reducers have become an indispensable part in the preparation of high-performance concrete. Among various types of high range water reducers, the comb-shaped structure polycarboxylate-based superplasticizer water reducers have the advantages of high water reduction rate, small loss of slump over time, and low dosage. They have become a research hotspot both at home and abroad. In the past decade or so, a large number of studies have focused on improving the performance of polycarboxylate-based superplasticizer water reducers by optimizing the molecular structure of polycarboxylates. For example, by adjusting the proportion of adsorption groups in the molecular structure, changing the molecular weight of the main side chain, and introducing functional third monomers, the water reduction performance, slump retention performance, and early strength performance of polycarboxylate-based superplasticizer water reducers can be effectively regulated.

Polycarboxylate Superplasticizer (PCE) 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.

Polycarboxylate 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. Polycarboxylate Superplasticizer (PCE) achieves its water reducing effect through the yield of electrostatic repulsion and steric hindrance when it is absorbed to the cement particles. Hence, Polycarboxylate Superplasticizer (PCE) is the most effective superplasticizer for cement concrete.

By correlating these structural information with the dispersion performance of the products, it was found that the dispersion performance of polycarboxylate superplasticizers is closely related to the polymer molecular weight, molecular weight distribution, and the conversion rate of the monomer. The study revealed that the polymer molecular weight should not be too large or too small; a product with an appropriate molecular weight has the best dispersion effect; when the polymer molecular weight is moderate, the superplasticizer with a narrow molecular weight distribution has better dispersion performance; a higher monomer conversion rate is equivalent to increasing the effective dosage of the polycarboxylate product, which is beneficial for enhancing the dispersion performance of the polycarboxylate superplasticizer. Polycarboxylate is a raw material for superplasticizer. It is recommended that applicants should determine the Polycarboxylate dosage in their own formulation according to their trial runs.
