Abstract:
A brief history of nondestructive testing of hardened concrete over the past 50 years is presented. The underlying principles and inherent limitations of the methods are reviewed, and historical highlights of their development are presented. Test methods are grouped into those that assess in-place strength and those that evaluate nonstrength characteristics, such as flaws and deterioration. Paper concludes with a discussion of the challenges for the 21st century in the area of nondestructive testing.
