Optical Imaging – Virginia Series

Optical Imaging – Virginia Series

A series of progressively greater magnification images of a pavement concrete from Virginia. Specimen in series was polished to more clearly show features. The interesting absence of entrained air voids appears to result from filling (of those which are visible.)
