PCEs are composed by a methoxy-polyethylene glycol copolymer (side chain) grafted with methacrylic acid
copolymer (main chain). The carboxylate group -COO−Na+ dissociates in water, provided a negative charge
along the PCE backbone. The polyethylene oxide (PEO or MPEG) group affords a non-uniform allotment of
electron cloud, which gives chemical polarity to the side chains.
The number and the length of side chains are flexible parameters that are easy to change. When the side
chains have a huge amount of EO units, they lower with their high molar mass the charge density of the
polymer, which enables poor performances on cement suspensions. To have both the parameters on the
same time, long side chain, and high indict density; one can keep the number of main-chain-units much
advanced than the number of side-chain-units.
PCE's backbone, which is unenthusiastically charged, permits the adsorption on the absolutely charged
colloidal particles. As an importance of PCE adsorption, the zeta potential of the balanced particles changes
due to the adsorption of the COO- groups on the colloid surface. This displacement of the polymer on the
particle outside ensures to the side chains the likelihood to put forth revulsion forces, which scatter the
particles of the suspension and avoid friction. These forces can be straight detected by the use of the atomic
force microscopy (AFM), working with model substances in liquid environment. Polycarboxylate ether shows
extremely high water reduction in concrete with improved workability and augments in strength by almost
20-30% depending on use. Polycarboxylate Ether super plasticizer shows good workability even when water
cement ratio is as low as 0.23.
