This　paper　proposes　a　new　type　of　lightweight　concrete　called　bubble　concrete,　which　was　developed　by　mixing　concrete　with　high-strength　hollow　bodies.　In　the　present　study,　concave　and　spherical　steel　hollow　bodies　were　used　not　only　to　form　multiple　cavities　in　the　concrete　but　also　to　transfer　internal　stresses.　Through　compression　tests,　the　shape　effects　and　distribution　effects　of　the　hollow　bodies　on　the　strength　and　Young＇s　modulus　of　concrete　were　investigated.　In　addition,　the　mechanical　characteristics　of　the　bubble　concrete　were　simulated　by　nonlinear　elastoplastic　finite　element　analysis　to　study　the　stress　distribution　and　failure　mechanism.　The　results　indicate　that　with　the　proper　combination,　bubble　concrete　can　reduce　its　density　to　1.971-2.003　g/cm(3)　(83.3-84.7%,　compared　to　control　concrete)　and　its　strength　reaches　27.536-28.954　N/mm(2).
