- 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.
