Slump-retaining concrete super plasticizer as well as preparation method and application thereof
The invention discloses a slump-retaining concrete super plasticizer as well as a preparation method and application thereof. The super plasticizer is obtained by copolycondensation of a phenyl-containing comb-shaped monomer A, a phenyl and phosphoric acid/phosphorous acid-containing monomer B, a phenyl and ester group-containing monomer C and an aldehyde monomer D. The concrete superplasticizer disclosed by the invention has good and excellent slump retaining capacity, particularly is relatively stable in fluidity change, has good adaptability to cement, and can meet the requirements of concrete with various materials and various slump requirements.
本发明公开了一种保坍型混凝土超塑化剂、其制备方法及应用。本发明所述超塑化剂由含苯基的梳形单体A、含有苯基和磷酸/亚磷酸的单体B、含有苯基和酯基的单体C和醛类单体D共缩聚得到。本发明所述混凝土超塑化剂具有良优异的保坍能力，尤其是流动度变化比较平稳，对水泥有良好的适应性，能够满足多种材料、多种坍落度要求的混凝土的需求。
