Evaluation and Adaptation of the Dobrolubov and Romer Method of Microscopic Examination of Hardened Concrete: Interim Report: Methods and Equipment Used in Preparing and Examining Fluorescent Ultrathin Sections

Report No: 78-R54

Published in 1978

About the report:

This report explains the methods and equipment used to produce fluorescent, impregnated, polished, ultrathin sections of portland cement concrete. These sections are used in the study of the microstructure of concrete and are examined with a microscope which combines the features of a petrographic microscope with those of a microscope having incident fluorescing capabilities. The unusual features of this microscope are detailed and brief instructions for the use of the instrument are given. A few of the features of the concrete made visible by use of this preparation method and microscope are shown in photomicrographs.
