Four　series　of　self-compacting　concrete(SCC)　specimens　containing　fly　ash,　two　series　of　SCC　specimens　containing　both　fly　ash　and　ground　granulated　blast　slag,　and　one　series　of　ordinary　concrete　specimens　without　mineral　admixture　added　were　prepared.　Using　the　accelerated　carbonation　test　method,　the　influences　of　tensile　stress　rates,　compressive　stress　rates,　and　use　level　of　mineral　admixture　on　the　carbonation　resistance　of　SCC　were　studied.　The　results　indicate　that,　under　all　stress　rates,　fly　ash　has　little　effect　on　carbonation　of　SCC　when　its　replacement　percentage　is　less　than　40%(by　mass),　but　the　carbonation　depth　increases　quickly　when　the　replacement　percentage　is　more　than　40%.　The　use　of　both　fly　ash　and　slag　greatly　improve　the　carbonation　resistance　of　SCC.　If　fly　ash　and　slag　admixture　ratio　is　1:1,　the　replacement　percentage　can　be　increased　to　60%.　The　carbonation　depth　of　SCC　increases　as　tensile　stress　rate　rises,　whereas　it　decreases　firstly　and　then　increases　as　compressive　stress　rate　rises.　The　relationship　between　carbonation　rate　and　stress　rate　was　also　established.　The　results　can　provide　a　method　for　establishing　the　model　for　predicting　the　carbonation　depth　of　SCC.
