The　crumb　rubberized　concrete　is　a　kind　of　new　type　building　material,　whose　aggregate　is　partly　replaced　by　the　crumb　rubber.　Rubberized　concrete　have　many　advantages　such　as　high　toughness,　elastic　properties　and　good　environmental　friendship.　However,　the　mechanical　properties　of　RCB　are　not　further　studied　up　to　now.　In　this　paper,　the　RCB　were　prepared　and　its　mechanical　properties　were　studied　by　the　cross-section　bending　experiments　of　the　beam,　such　as　damage　characteristics,　load　characteristics,　displacement　characteristics,　and　the　beam　stress-strain　curves,　etc.　The　finite　element　program　ANSYS　was　used　to　simulate　the　mechanical　properties　of　the　RCB.　The　results　show　that,　RCB　has　good　ductility　and　energy　dissipation　capacity,　and　the　test　results　and　simulation　analysis　are　consistent.
