Abstract:
The scanning electron microscope (SEM) has become a standard analytical tool used by a wide range of investigators to analyze materials failures of many types. This paper explains how the scanning electron microscope can be used for postmortem analyses of corrosion and cracking problems in a variety of metal-reinforced concrete systems. Applications to research and forensic analysis are discussed.
