Polycarboxylate ether

Chemical Materials

Polycarboxylate ether (PCE) Superplasticizers, also known as high range water reducers, are chemicals used as concrete admixtures. SCC (self compacting concrete) is the best example for PCE. Polycarboxylate superplasticizer has drawn more and more attention in modern construction industry because of its superior dispersibility and retention effects.
