Table 5 Concrete cracking parameters under strong wind and cold wave conditions.
From: RETRACTED ARTICLE: Research on Construction Risks and Countermeasures of Concrete Dam
Treatment measures | Average cracking area of each crack (mm2/strip) | Number of cracks per unit area (strip/m2) | Total cracking area per unit area (mm2/m2) | Average maximum crack width (mm) |
|---|---|---|---|---|
Surface nontreatment | 27.3 | 12.5 | 342 | 0.11 |
Covering insulation quilt | 0.0 | 0.0 | 0.0 | 0.0 |
Add PVA fibers | 12.9 | 6.3 | 81 | 0.05 |
