摘要
The present invention discloses a method for preparing a concrete superplasticizer having a phosphorous acid group and a use of the concrete superplasticizer. The concrete superplasticizer having a phosphorous acid group according to the present invention is prepared by free radical copolymerization of a phosphorous-containing monomer A and a polyether macromonomer B. The concrete superplasticizer having a phosphorous acid group obtained in the present invention can effectively improve flowability of concrete and can retain good workability of concrete. The method is simple, economical and effective, and in particular, can be used for commercial mass production.
