In　order　to　testify　whether　the　traffic　vibrations　at　early　concrete　ages　would　affect　the　concrete　segregation　and　compress　strength,　a　series　of　vibration　tests　with　five　different　vibration　acceleration　values　were　conducted　to　the　fresh　concrete　with　slumps　of　70　mm,　120　mm　and　160　mm　respectively.　According　to　the　test　results,　the　segregation　of　the　vibrated　concrete　tends　to　be　stable　with　the　vibration　time　lasting.　The　slump　of　the　concrete　influences　the　concrete　segregation　only　when　vibration　energy　is　high.　Based　on　the　relationship　between　the　compress　strength　of　the　vibrated　concrete　and　their　segregation　factor,　low　level　vibration　energy　increases　the　concrete　compress　strength　and　high　level　vibration　energy　and　high　slump　decreases　the　compressive　strength　of　concrete.　©　2016,　Beijing　University　of　Technology.　All　right　reserved.
