Abstract

The identification of the physical and mechanical characteristics of the material of the structures used by non-destructive methods of determination has significant limitations. They are caused by differences in concrete composition, structural structure parameters and measurement conditions. A significant factor in the reliability of non-destructive methods of determination is the personal factor that depends on the expert performing the determination. Ultrasonic vibration propagation time measurements were performed using a Pulsar 1.1 and Novotest IPSM-U instrument for changes in the pressing force of the device to the sample concrete within the limits recommended by the device manufacturers and smaller. The time of propagation of ultrasonic vibrations during the change of the force of pressing the device to the surface of concrete of different compositions has been determined. It has been established that the dependence “time of propagation of ultrasonic vibrations—force of pressing the device” is approximated linearly with the highest accuracy if this dependence is divided into three intervals. The first and the third intervals are characterized by a slow change of properties, the second—by a sharp one. Studies have confirmed that the results of the measurements were influenced by the force of pressing the device to the surface, the composition of concrete and the conditions of structure construction. Improving the accuracy of determining the physical and mechanical characteristics of the material of structures appears to be possible taking into account the above-mentioned factors.
