“…In concrete construction engineering, US-T waves are conventionally employed for the nondestructive diagnostics of structural conditions, including flaw detection or damage development [40][41][42][43][44][45]; for early-age hardening monitoring to aid technological processes like formwork removal, aggregate exposure, etc. [45][46][47][48][49][50][51][52]; and also for concrete demolition works.…”

“…Azenha et al [21] continuously monitored the evolution of elastic modulus of a prefabricated beam through modal analysis. Haach and Juliani [22] evaluated the possible application of ultrasonic tests for the technological control of concrete of hollow-core slabs in the production phase and concluded UPV tests can be an interesting alternative for use in precast concrete industries.…”

“…Ao contrário da literatura, os autores indicaram que a armadura reduziu as velocidades obtidas na parede de concreto. Isto pode ser justificado pelo diâmetro das barras de aço e proximidade entre elas, o que pode causar interferências no percurso do pulso ultrassônico, durante leituras com transmissão indireta Haach, et al (2017). realizaram um estudo para verificar a possibilidade da utilização da técnica de ultrassom para o controle tecnológico da concretagem de lajes alveolares durante o período de cura.…”
