| 要旨 |
This study investigates the anisotropic expansion of concrete affected by Delayed Ettringite Formation (DEF) under uniaxial restraint conditions. Utilizing a device designed to impose varying levels of restraint, the research examines concrete samples with rebar ratios of 0%, 0.75%, 1.34%, and 2.10%. The anisotropic characteristics of expansive behavior was also evaluated, and the study uniquely employs expansive energy as a key metric to analyze the expansive potential, providing valuable insights into the influence of uniaxial restraint on DEF-affected concrete. |
