scope:

This report focuses on practices used to evaluate concrete in existing massive structures. Design considerations, evaluation of existing operating records and past inspection reports, condition surveys, maintenance reports, determination of in-place conditions, instrumentation, identification of damage, and final evaluation of concrete are principal subjects that are covered. The objective of this report is to present methods for evaluating the capability of mass concrete to meet design criteria under service conditions, and to present procedures to detect the change in physical properties of concrete that could affect the capability of the concrete to meet future performance requirements.
