Erratum: Visualization and evaluation of concrete damage in-service headworks by X-ray CT and non-destructive inspection methods

Abstract

Morozova N, Shibano K, Shimamoto Y, Tayfur S, Alver N and Suzuki T (2022) Visualization and evaluation of concrete damage in-service headworks by X-ray CT and non-destructive inspection methods. Front. Built Environ. 8:947759. doi: 10.3389/fbuil.2022.947759Due to a production error, there was a mistake in Table 3 as published. The table columns were left aligned instead of right aligned. The corrected Table 3 appears below. Due to a production error, the text of the last paragraph of the Introduction on page 3 was duplicated.The corrected paragraph is as follows:"In this study, damage evaluation of concrete core samples is investigated by applying NDT parameters. The samples were taken from an in-service reinforced concrete structure, which has been subjected to the influence of aggressive environmental effects. Then, X-ray CT procedure was conducted on the specimens to detect and visualize the crack distributions After scanning, concrete damage was evaluated by the dynamic modulus of elasticity measured by UPV and resonant frequency tests. Results indicate that the decrease in mechanical properties of the concrete could be evaluated by comparing the geometrical properties of cracks with the dynamic modulus of elasticity, because both these parameters are affected by the internal actual cracks, thus, the damage of concrete could be quantitatively evaluated."The publisher apologizes for these mistakes. The original version of this article has been updated.
