Table 4 Concrete cracking parameters under the coupled conditions of strong wind, dryness, and heat.
From: RETRACTED ARTICLE: Research on Construction Risks and Countermeasures of Concrete Dam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 | 26.4 | 10.4 | 275 | 0.14 |
Covering insulation quilt | 10.0 | 4.2 | 42 | 0.18 |
Add PVA fibers | 7.8 | 8.3 | 65 | 0.04 |
