The molecule of polycarboxylic acid (salt) water reducer is a "comb" or "dendritic" structure artificially formed by "molecular design", and there are many branch chains (side chains) with a certain length and stiffness on the molecular main chain. There are also sulfonates or other groups on the main chain that can make the cement particles charged, which can play the role of traditional water reducing agents, and more importantly, once the main chain is adsorbed on the surface of the cement particles, the branch chain forms a three-dimensional cross with the branch chain on the surface of other particles, preventing the particles from approaching each other, so as to achieve dispersion (that is, water reduction). This steric hindrance does not weaken with the extension of time, so the dispersion of polycarboxylic acid superplasticizer is more lasting.
