WHAT IS POLYCARBOXYLATE – Polycarboxylic Ether

WHAT IS POLYCARBOXYLATE. Polycarboxylate (PCE) superplasticizers are known as high range water-reducing admixtures in concretes, such as ready-mix concretes, self-compacting concretes (SCC), ultra-high strength concretes (UHPC) and at the same time give an extended slump retention.. Polycarboxylate Ethers improve the rheology of concrete through the dispersion of particles.
