Abstract:
Scanning electron microscopy has distinct advantages for
characterization of concrete, cement, and aggregate
microstructure, and in the interpretation of causes for
concrete deterioration. Scanning electron microscope
imaging facilitates identification of hardened cement
paste constituents with greater contrast, and greater
spatial resolution than for optical methods and provides
ancillary capability for element analysis and imaging.
Quantitative information may be extracted from these
data, such as composition, phase abundance and
distribution. Sample preparation and demonstration of
some of the common imaging techniques and extraction of
data using image processing and analysis are presented.
