To　change　the　characteristics　of　brittle　failure　and　easy　cracking　of　the　concrete,　a　novel　method　of　mixing　materials　with　different　scales　into　concrete　to　inhibit　the　generation　and　development　of　cracks　is　proposed.　Taking　carbon　nanotubes　(CNTs),　calcium　carbonate　whisker　(CCW),　polyvinyl　alcohol　(PVA)　fiber,　steel　fiber　and　rubber　particles　as　the　experimental　materials,　the　multi-scale　modified　concrete　compression　test　was　carried　out.　According　to　the　test　results,　the　effects　of　different　materials　on　the　mechanical　properties　of　concrete　are　analyzed,　and　the　optimal　content　scheme　of　materials　is　determined.　In　view　of　the　damage　constitutive　and　damage　variables　based　on　the　Weibull　distribution　cannot　comprehensively　reveal　the　me-chanical　properties　and　damage　state　of　concrete,　the　combined　damage　variable,　the　damage　variable　based　on　energy　method　and　the　corresponding　damage　constitutive　model　are　presented.　To　synthetically　evaluate　the　mechanical　properties　of　concrete　from　the　perspective　of　damage,　the　modified　damage　variable　is　proposed　considering　the　influence　of　concrete　compressive　strength.　The　analysis　results　show　that　the　optimal　content　of　CNTs,　CCW,　PVA　fiber,　steel　fiber　and　rubber　particles　are　0.6%,　6%,　0.075%,　1%　and　0%,　respectively.　The　damage　variable　based　on　the　energy　method　has　a　clear　damage　mechanism　and　can　accurately　represent　the　performance　state　of　concrete.　The　modified　damage　variable　can　significantly　distinguish　the　comprehensive　performance　of　different　concretes.　In　addition,　the　scanning　electron　microscope　results　verified　that　CNTs,　CCW,　PVA　fiber　and　steel　fiber　can　inhibit　the　development　of　cracks　through　the　bridging　effect　to　change　the　failure　pattern　of　concrete.
