Water-reducing admixture is a concrete admixture that can reduce mixing water consumption while maintaining the slump of concrete basically unchanged.
After being added to the concrete mixture, it has a dispersing effect on the cement particles, which can improve its workability, reduce the unit water consumption, and improve the fluidity of the concrete mixture; or reduce the unit cement consumption and save cement amount.
