Bricks built in Masonry: Influence of Sounding Techniques and Moisture on Ultrasonic Pulse Transmission Velocity During Parameter Determination

Popis výsledku v původním jazyce

When examining brickwork, also ultrasonic pulse method is used to determinate the material properties such as strength, modulus of elasticity, and so on. In general terms, test results are influenced by many factors such as length of measuring base, probe frequency, specimen dimensions, moisture, and internal structure or its defects, and the like. Bricks built in masonry can show various moisture and structure values, but also defects related to manufacturing technology which are acceptable in the light of use nevertheless, they influence test results when testing the bricks by ultrasonic pulse method. Analysis of findings concerning the influence of moisture and brick sounding technique implies that test results are influenced in varying degrees. Thehighest reproducibility ratio is shown in case of calcium silicate bricks and the lowest one occurs with extruded clay bricks. Here, synergic action of moisture, state of structure (porosity), and clinker defects are manifested. To inter
