Concrete Microscopy
Concrete microstructure can be evaluated using both thin and polished sections. Methods described in this report were developed as a supplement to ASTM 856 procedures. The use of an epoxy resin containing a fluorescent dye tended to enhance the ability to view porosity and mechanical features such as interface porosity and cracking. Relationships of formulation and microstructure for a series of nineteen concrete samples are presented. The proposed methods are useful to the highway engineer on a variety of levels. The determination of water/cement (w/c) ratio is more difficult since it is done by visually comparing the fluorescence intensity of the unknown with a series of known standards.
