Abstract

The invention discloses a concrete water reducing agent. The concrete water reducing agent is prepared from HPEG water reducing monomers, TPEG slump retaining monomers, mercaptopropionic acid, sodiumhypophosphite, acrylic acid, hydroxyethyl acrylate, maleic anhydride, vitamin C, liquid alkali NaOH, hydrogen peroxide, dextrin, APS ammonium persulfate and deionized water. The invention also discloses a preparation method of the concrete water reducing agent. The method comprises the following steps: preparing raw materials, preparing a mixed solution, adding hydrogen peroxide and performing mixing and stirring to obtain a finished product. The concrete water reducing agent has the beneficial effects that cohesiveness of a concrete mixture can be increased by addition of dextrin, and segregation and bleeding of concrete can be effectively improved; the concrete water reducing agent is easy to prepare, and energy consumption is reduced; the prepared concrete water reducing agent has goodslump retaining property.
