Abstract:
Describes the application of two nondestructive impulse methods, viz., the ultrasonic and the sonic hammer methods for checking the quality of concrete. Compares the two methods and gives their advantages and disadvantages especially in relation to speeding up the construction of prestressed concrete bridges.
