Comparison of Fresh Concrete Air Content Methods & Analysis of Hardened Air Content in Wisconsin Pavements
| 项目名称： | Comparison of Fresh Concrete Air Content Methods & Analysis of Hardened Air Content in Wisconsin Pavements |
| 摘要： | Wisconsin Department of Transportation (WisDOT) and others have noted disparities between measured air entrainment as measured by the ASTM C231B pressure meter method and by ASTM C457 analysis of hardened concrete specimens. This proposal seeks to identify the source of this disparity and determine whether existing techniques for measuring fresh air content continue to be suitable for contemporary air entraining admixtures. |
