Progresses in Synthesis of Polycarboxylate Superplasticizer
Polycarboxylate superplasticizer (PCE) was synthesized by unsaturated monomers of carboxylic acid, alkane macromonomers of long chains, and others. It was an excellent cement dispersant which would make great performance in concrete [ 1 ].
Research progress on polycarboxylate based superplasticizers
Polycarboxylate ether/ester (PCE) superplasticizers are widely used due to their molecular structural designability, low dosage and high efficiency. However, their high sensitivity and strong interactions with clays in concrete reduce their dispersion and water-reduction capability, which can affect the performance of concrete seriously.

Low-cost synthesis of high-performance polycarboxylic ether
As a new type of high-performance water-reducing agent, polycarboxylate ether (PCE) has excellent properties such as small dosage and high water reduction rate. However, it is still necessary to develop a synthetic process to improve the performance of PCE at a low cost.
- Do Polycarboxylate ether/ester superplasticizers affect concrete performance?
- Polycarboxylate ether/ester (PCE) superplasticizers are widely used due to their molecular structural designability, low dosage and high efficiency. However, their high sensitivity and strong interactions with clays in concrete reduce their dispersion and water-reduction capability, which can affect the performance of concrete seriously.
