| 要旨 | Reinforced concrete prism with w/b ratio of 0.5 had dimensions of 150x150x500 mm, while concrete cover were 30 mm, 50 mm and 70 mm. The crack widths investigated were 0.3 mm and 0.5 mm. These specimens were exposed to three conditions: (1) dry-wet cycles in tap water; (2) dry-wet cycles in sea-water; and (3) continuously immersed in 3% NaCl solution. The results show crack width has influence at constant concrete cover. However, by increasing concrete cover, the crack width has less affected. Further, exposure condition and SCMs (BFS) has an effect particularly in high chloride environment. |
