The application of ultrasonic wave to nondestructive testing of concrete structure was studied.
It was shown that the induced frequency adeguate to concrete is about 50KHz and the influence of test condition must be considered. The propaigation characteristics of ultrasonc wave in concrete make possible to estimate strength, damage and depth of cracks, etc.
The specification of standard reqiurements for acoustic properties of concrete and many laboratory investigations are required for effective application to industrial practice.
