Polycarboxylates are comb-like copolymers with a succession of methacrylic acid models in the most crucial chain, in addition to a substitution of aspect of those methacrylic acid units by poly (ethylene glycol) methyl ether methacrylate, forming side chains from the primary chain.[9,ten] It is thought from different scientific studies within the system of motion of superplasticizers that the success with the molecules used is based on two distinct effects.[eleven] Very first, the negatively billed acid groups of the plasticizers are adsorbed over the positively charged cement particle area resulting from calcium ions.[ten] The electrostatic double layer shaped in this manner (zeta likely) leads to electrostatic repulsion involving the particles, but this is comparatively weak.
