Abstract

The purpose of this study is to suggest the fundamental data of durability which effects on the Carbonation of concrete by adding various admixture additives. Thus, We have experimented the accelerated test on the concrete blending which was admixed by blast furnace slag, fly-ash, silica fume , durability amelioration and it was cured 7weeks after twenty eight days water curing. The result of this experiment is that Carbonation speed increased extremely when water cement ratio went up, and by growing of replace cement ratio of admixture additives. The specimen which was added fly-ash, blast furnace slag, silica fume has the faster Carbonation speed than the specimen which was not added admixture additives. All of these specimen, fly-ash has the fastest progress speed.
