Development of Procedures for Nondestructive Testing of Concrete Structures. Report 1. Present Practices.

摘要

The Concrete Laboratory (CL) has used nondestructive testing (NDT) in the evaluation of concrete and concreting materials. In recent years, more emphasis has been placed on the inspection and structural evaluation of completed Corps of Engineers structures. The need for a capability to predict, prior to placement, certain properties of concrete mixtures after hardening has been realized. This report discusses the history, progress to date, and needs for future research and development in the field of NDT.
