This handbook provides a thorough analysis of nondestructive testing used to evaluate concrete structures. It examines the tools and techniques used to estimate the in-place strength of concrete and permeation properties that relate to potential durability and describes the methods used to assess the condition of concrete integrity and steel reinforcement. The authors of each chapter are recognized specialists in the field of nondestructive testing. They discuss the basic methodological principles and offer practical guidance for their use. The book refers to numerous original papers for those interested in more detailed information in lieu of extensive mathematical derivations.
