This project will investigate a nondestructive test method which will           be used to detect and locate flaws in concrete structures.  Method              under investigation is the impact-echo technique which has proven               successful on plate-like structures such as slabs and pavements.                Analytical studies, together with experimental investigations, will be          conducted to verify the technique for beams and columns.
