Cover: Crack data was obtained by analyzing CT slices individually. Due to the volumetric expansion of the corrosion products from the steel bar, the corrosion-induced cracks extended along the steel bar to the concrete surface. The initiation location of the corrosion-induced crack was in the region of the peripheral corrosion products of the steel bar, and the end position was located inside or on the surface of the concrete.
