I　this　work,the　effects　of　standard　curing,saturated　Ca(OH)2　solution　curing　and　autoclave　curing　on　the　corrosion　of　reinforcement　in　alkali-activated　slag　concrete　with　CaO+Na2CO3　as　the　exciter　(CNC)were　investigated　under　accelerated　carbonation　environment　(CO2　concentration　of　20%).　The　results　show　that　compared　with　standard　curing,saturated　Ca(OH)2　solution　curing　does　not　change　the　hydration　products　of　CNC　but　can　make　the　early　hydration　of　CNC　more　sufficient.　Therefore,the　average　pore　size　decreases.　Autoclaving　curing　converts　the　hydration　products　of　CNC　from　C-S-H　gel　into　hydrogarnet　and　11-?　type　tobermorite.　Therefore,the　average　pore　size　and　total　porosity　decrease　significantly.　Under　the　same　accelerated　carbonization　conditions,compared　with　standard　curing,the　carbonization　depth　of　CNC　decreased,the　high　probability　corrosion　time　of　reinforcement　in　CNC　delayed,and　the　weight　loss　rate　of　reinforcement　in　CNC　decreased　both　in　saturated　Ca(OH)2　solution　curing　and　in　autoclaving　curing.　Under　the　same　curing　conditions,the　corrosion　resistance　of　steel　bars　in　CNC　cured　by　standard　curing　and　saturated　Ca(OH)2　solution　is　much　less　than　that　in　ordinary　Portland　cement　concrete.　The　corrosion　resistance　of　steel　bars　in　CNC　cured　by　autoclaving　was　better　than　that　in　ordinary　Portland　cement　concrete.　©　2024　Cailiao　Daobaoshe/　Materials　Review.　All　rights　reserved.
