SILVA, M. T. A. et al. Evaluation of the ultrasound test for estimating the depth of cracks in concrete. Rev. ALCONPAT [online]. 2019, vol.9, n.1, pp.79-92. Epub 29-Set-2020. ISSN 2007-6835. https://doi.org/10.21041/ra.v9i1.289.
The objective of this study is to evaluate the ultrasound test to estimate the depth of cracks in concrete, using a mathematical model published in the literature, and to verify this depth with more accurate results. Four concrete test specimens were molded for each proposed crack depth (5 cm, 10 cm, and 15 cm), simulated using zinc plates, placed during molding and removed before concrete hardening. The results show that the test is sensitive enough to detect the presence of the cracks in the concrete. The mathematical model used allowed for an estimation of the depths of most cracks, but the results are scattered and have a high margin of error for the depths of 5 cm and 15 cm. The cracks of 10-cm depth produced better results.
