3. Ultrasonic Flaw Detection Test :
Ultrasonic testing is completely nondestructive
and safe, and it is a well established test
method in many basic manufacturing,
process, and service industries, especially in
applications involving welds and structural
metals.

4. Ultrasonic Pulse Velocity Test :
Ultrasonic concrete testing is based on the
pulse velocity method to provide information
on the uniformity of concrete, cavities, cracks
and defects. The pulse velocity in a material
depends on its density and its elastic
properties which in turn are related to the
quality and the compressive strength of the
concrete.

5. 
The pulse velocity in concrete may be
influenced by
a) Path length
b) Lateral dimension of the specimen tested
c) Presence of reinforcement steel
d) Moisture content of the concrete
