Table 5: Average and standard deviation of the angular positions (in degrees) of internal cracks. corner rebar [18; 20; 33; 38; 56; 60; 64]. The number of cracks described in these studies varies between one and six cracks. In all cases, the main cracks are vertical and/or horizontal. These cracks usually propagate throughout the concrete cover and become externally visible. Our findings are in accordance with those previously reported in the literature. Very few studies have measured the width of corrosion-induced internal cracks located in close proximity to the rebar [22; 25; 26; 63]. In these studies, experiments focused on corrosion-induced cover cracking due to centre rebars. To our knowledge, no published work to date has measured internal cracks (width and length) in samples with a rebar in the corner.
