| 内容記述 | This study is aimed at exploring the anisotropy of expansion and cracking in concrete induced by alkali–silica Reaction (ASR) under constraint conditions imposed by rebars. In ASR-affected concrete, expansion is suppressed along constrained directions and redirected to less constrained directions, a phenomenon known as expansion transfer. This phenomenon is analyzed using concrete prisms embedded with rebars to investigate the influence of the bond between concrete and the rebar on crack distribution and orientation. The findings reveal that cracks align with the direction of least restraint, exhibiting distinctive orientations in the presence of rebars. The internal crack distribution can be estimated using surface crack patterns. Furthermore, a crack directionality index, defined as the ratio of transverse to longitudinal crack densities, is proposed to quantify the anisotropy of expansion. | |||||||||||
