Abstract

Concrete is the most widely used material to construct critical large infrastructure systems such as dams, bridges and nuclear power plants. These concrete structures are generally subjected to various degradation mechanisms including alkali-silica reaction (ASR), freezing-thawing cycles and steel bar corrosion during their service life. Prolonged and repeated exposure to these mechanisms can result in distributed cracking in the structures. This paper presents a contactless ultrasonic wavefield imaging approach for visualizing distributed cracks in concrete.
