Global polycarboxylate ether (PCE) market is segmented into product and geography. 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.
