Abstract
W artykule przedstawiono próbę nieniszczącej lokalizacji zbrojenia w elemencie betonowym z zastosowaniem nowoczesnej nieniszczącej metody badawczej tomografii ultradźwiękowej. Metoda ta nie jest wprawdzie przeznaczona do lokalizacji zbrojenia, ale podczas testów laboratoryjnych otrzymano interesujące wyniki, które zamieszczono w niniejszej pracy. Były to sygnały, jakie otrzymano dla próbki betonowej wykonanej w laboratorium, w której umieszczono zamodelowaną siatkę prętów zbrojeniowych. Analiza uzyskanych rezultatów wykazała, że jest możliwe określenie lokalizacji siatki zbrojeniowej za pomocą metody tomografii ultradźwiękowej, ale do głębokości ok.200 mm elementu betonowego. Zwrócono uwagę, że potrzebe większej liczby takich sygnałów (zobrazowań) wzorcowych, które mogą być przydatne do monitoringu i diagnostyki obiektów wykonanych z betonu.
Ultrasonic tomography method non-destructive testing of location reinforcement in the concrete element
abstract
The paper presents the location of the non-destructive test of reinforcement in concrete element with the use of modern non-destructive testing method of ultrasonic tomography. This method is indeed dedicated to the location of the reinforcement, but during laboratory tests gave interesting results, which are presented in this paper. There were signals that were obtained for the samples of con- crete performed in the laboratory, which provided a grid of reinforcing bars modeled. Analysis of the results showed that it is possible to determine the location of the reinforc- ing fabric by the method of ultrasonic tomography, but to a depth of about 200 mm of the concrete element. It was noted that there is a need to develop more of these signals (imaging) model, which can be useful for monitoring and diagnosis of buildings made of concrete.
