The polycarboxylate ether comb-polymers consist of a polycarboxylate backbone and polyethylene oxide side chains bound to the backbone as esters. Polycarboxylate ether liquid is a high performance superplasticizer and water reducer for concrete. It can create a water reduction up to 40% with relatively low dosage (about 0.02-0.3% by cement weight) It is mainly used as a raw materials to produce different types of high performance concrete admixtures for targeted industries.
