The 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 also 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 who have served in technical committees on nondestructive testing. The chapters discuss the basic principles of the methods and offers practical guidance for their use. Extensive mathematical derivations are kept to a minimum; instead the Handbook refers to numerous original papers for those interested in more detailed information.
