The　influence　of　rubber　particles　type　and　rubber　particles　dosage　and　NaOH　solution　pretreatment　of　rubber　particles　on　the　fracture　property　of　rubberized　self-compacting　concrete　is　researched　by　three-point　bending　rest.　The　load-displacement　curves　and　load-crack　opening　mouth　displacement　curves　of　the　specimens　are　measured.　The　initiation　fracture　toughness　and　unstable　fracture　toughness　and　fracture　energy　are　calculated　based　on　double-K　fracture　model.　The　result　indicates　that　incorporating　rubber　particles　to　self-compacting　concrete　can　improve　the　fracture　toughness　and　fracture　energy　obviously;　the　increase　amplitude　is　affected　by　rubber　content,　variety.　NaOH　solution　pretreatment　particles　can　improve　rubberized　self-compacting　concrete　fracture　properties　of　rubber.　©,　2015,　China　Water　Power　Press.　All　right　reserved.
