| Abstract: | Study was focused on preparation technology of the high range water reducing agents of polycarboxylic series with rom methacrylic acid, acrylic acid and methoxypolyethyleneglycol as the main raw materials while study was also carried out for influencing factors of reactants proportion ,content of initiator and reaction time, etc. The product was characterized and analyzed by FT-IR. Furthermore, tests were made on properties of the reducer such as cement paste fluidity. Eventually, a good water-reducing admixture suitable for high-performance concrete was obtained. |
