摘要：

The　physical　and　mechanical　properties　of　Crumb　Rubber　Recycled　Aggregate　Concrete　(CRRAC)　are　studied.　The　test　results　show　that　the　workability　of　fresh　CRRAC　is　improved　by　incorporating　of　crumb　rubber,　and　the　density　of　CRRAC　can　be　reduced　significantly.　The　compressive　strength　and　splitting　strength　of　CRRAC　are　close　to　that　of　crumb　rubber　concrete,　but　much　lower　than　that　of　recycled　aggregate　concrete.　After　modified　by　redispersible　polymer　powder　which　plays　a　role　of　＇bridge＇　it　improves　the　crack　resistance　ability　of　CRRAC.　The　ratio　between　splitting　strength　and　compressive　strength　increases　significantly.　That　means　the　plastic　deformation　capacity　of　CRRAC　was　improved.
