Ultrasonic Testing Of Non Metallic Materials Concrete And Marble

Using the ultrasonic ndt method.

Ultrasonic testing of non metallic materials concrete and marble.

C 2004 elsevier ltd. The present experimental work will examine the behavior of a 30 year old concrete and a dionysos pentelikon marble using destructive as well as the ultrasonic non destructive testing methods. Examined in the work are construction materials such as concrete and marble. None of the available non destructive methods for testing concrete and marble seem to provide a better answer.

Among the known methods the ultrasonics seem to stand out because the method could be used to determine many properties of the material. The upv methods have traditionally been used for the quality control of materials mostly homogeneous materials such as metals and welded connections. Similar work has been done by vardoulakis 2 and the values obtained. The ultrasonic method can be applied to specimens for new construction and for in situ examination using longitudinal ultrasonic waves.

Ultrasonic testing of marbles has been examined by several researchers 1 6. In particular the dynamic moduli of elasticity and damage states due to fracture are studied. Elasticity moduli shear moduli and poisson ratio of marbles and concrete have been determined by ultrasonic waves under varied pressure 1. Examined in the work are construction materials such as concrete and marble.
