摘要：

Based　on　carbonation-only　test,　freezing-thawing-cycle-only　test　and　alternate　test　between　carbonation　and　freezing-thawing　cycles,　relative　compressive　strength,　relative　dynamic　modulus　of　elasticity　and　carbonation　depth　of　concrete　were　measured　and　analyzed.　Test　data　show　that　for　the　alternate　actions　between　carbonation　and　freezing-thawing　cycles,　relative　compressive　strength　of　concrete　is　higher　than　that　exposed　to　freezing-thawing-cycle-only　process,　but　the　increase　is　limited;　its　relative　dynamic　modulus　of　elasticity　is　lower　than　that　exposed　to　freezing-thawing-cycle-only　process;　whereas　its　carbonation　depth　is　larger　than　that　exposed　to　carbonation-only　process.　The　frost　resistance　and　carbonation　resistance　of　concrete　decrease　compared　to　that　exposed　to　freezing-thawing-cycle-only　and　carbonation-only　processes,　respectively.　Finally,　a　compressive　strength　fitting　model　subjected　to　the　alternate　actions　between　carbonation　and　freezing-thawing　cycles　is　established,　in　which　two　independent　variables(carbonation　time　and　number　of　freezing-thawing　cycles)　are　taken　into　account.　©　2017,　Editorial　Department　of　Journal　of　Building　Materials.　All　right　reserved.
