    Abstract

    The method of preparation is explained for fluorescent dye-impregnated polished ultrathin sections of portland cement concrete used for a study of the microstructure of concrete. The sections were examined with a microscope that combines the features of a petrographic microscope with those of a microscope having incident fluorescing capabilities. Photomicrographs are used to illustrate microcracks, hollow shell hydration, impermeable areas, and the influence of coatings on aggregate particles.
