Incorporation　of　silane　groups　into　polycarboxylate　superplasticizer　(PCE)　opens　a　new　technical　approach　to　improve　properties　of　PCE,　such　as　to　enhance　the　adsorption　of　PCE　on　cement　and　hence　the　dispersing　performance,　to　minimize　the　retardation　effect,　and　potentially　to　increase　mechanical　strength　of　cement　mortars.　Silylated　PCEs　were　synthesized　using　silane　monomer　via　radical　copolymerization.　Dispersing　effect,　adsorption　behaviors,　and　influences　on　mortar　strength　of　these　polymers　were　systematically　investigated.　Results　show　that　increasing　the　incorporation　of　sliane　groups　in　PCE　promotes　the　adsorption　of　polymer　on　cement　surface　and　hence　leads　to　good　fluidity　retention　capability.　Furthermore,　sulfate　resistance　ability　of　silylated　PCE　is　superior　due　to　stronger　chemical　adsorption　of　polymer　on　cement　surface.　The　retardation　effect　of　PCE　is　minimized　by　the　introduction　of　silane　groups.　The　addition　of　silylated　PCE　significantly　increases　3days　compressive　strength　without　notably　affecting　the　long-term　strength.　(c)　2016　Wiley　Periodicals,　Inc.　J.　Appl.　Polym.　Sci.　2016,　133,　44161.
