| v| | In order to attain frost resistance of concrete structures, the air void system in hardened concrete has an important role. As a target of RC slab in this study, the air void characteristics of concrete were investigated with the different mix proportions and the execution conditions on actual construction. From these results, it was shown that the air void frequency increase with water-binder ratio decrease, especially the diameter 0-200สm. Confirming the range of air void 0-200สm was one of the significant factors of featuring the distribution of air void and the spacing factor. |
