摘要：

A　superplasticizer　was　synthesized　by　maleic　anhydride　and　isoprenyl-PE-PPG　according　to　molecular　structure　design　principle.　The　molecular　structure　of　superplasticizer　was　determined　by　Fourier　transform　infrared　spectroscopy,　1H　nuclear　magnetic　resonance　and　gel　permeation　chromatography,　respectively.　The　surface　tension,　adsorption　behavior,　zeta　potential,　the　flow　behaviour　of　superplasticized　cement　paste,　rheological　behavior　of　cement　pastes,　and　application　performance　in　concrete　have　been　measured.　Results　of　evaluation　on　performance　have　showed　that　superplasticizer　has　good　viscosity-reducing　effect　and　the　mechanism　of　superplasticizer　has　been　analyzed.　©　2021,　Materials　Review　Magazine.　All　right　reserved.
