Abstract
Concrete materials are impregnated with liquids which harden within concrete pores and microcracks, and develop a sharp contrast with the body of concrete in microscopic images. The impregnation process involves vacuum application to remove air from concrete pores and microcracks, followed by the introduction of liquids under pressure. The sharp contrast between the impregnated (and hardened) liquid and the body of concrete facilitates distinction of pores and microcracks in microscopic images for the purpose of automated image analysis.
