Influence of a polymeric covering and inclusions in concrete on parameter’s variation of propagation ultrasonic waves
For accident-free work of pipeline made heavier by a concrete layer not only mass but also durability, integrity and resilient properties of concrete is important. On the stage of reception of pipe on building it is suggested to check up the concrete layer of pipe through an ultrasonic method. In this case difficulty of diagnostics of concrete consists of absence of bilateral approach. This article reveals problems an accessible surface is hidden under a polymeric layer. This article reveals how defects in a concrete to influence on the parameter’s variation of ultrasonic wave.
