چکیده

Abstract An ultrasonic technique has been experimented for non destructive testing of building structures. The Through Transmission Technique has been applied, processing the wave incident on a grid of detecting probes after it has been transmitted through a trachite stone masonry with an inside cavity. Several parameters associated with acoustic waves propagating through the structure have been analyzed and a distribution map of each feature has been built using the data acquired in the grid’s nodes. Moreover, a novel approach based on the clustering of an high dimensional features space has been tested for data interpretation. Preliminary results confirmed the suitability of the proposed approach to non destructive testing of building materials.

Sand/cement ratio evaluation on mortar using neural networks and ultrasonic transmission inspection.

The quality and degradation state of building materials can be determined by nondestructive testing (NDT). These materials are composed of a cementitious matrix and particles or fragments of aggregates. Sand/cement ratio (s/c) provides the final material quality; however, the sand content can mask the matrix properties in a nondestructive measurement. Therefore, s/c ratio estimation is needed i...

Time, Wavelet and Hilbert-Huang Domain Analysis of Signals from Ultrasonic Based NDT

In this paper we compare the effectiveness of the time, wavelet and Hilbert Huang domain analysis of waveforms from a Non Destructive Test (NDT) equipment. The analysis of the signals from NDT systems is one of the most important activities since it allows to locate the actual defects. Very often the echoes traveling back to the sensors are superimposed with the signal from the transducer. We a...
