Abstract: In order to study the flexural behavior of structures exposed to severe environmental condition as like in case of marine structures in corrosive environment, a powerful nondestructive technique as a structural health monitoring tool needed to be employed. Acoustic emission (AE) is one of the most powerful nondestructive technique widely used for corrosion assessment of steel embedded in concrete as well as to study the behavior of RC beams under flexure. The presence of corrosion affects the flexural behavior structural elements. Hence it is necessary to interpret and evaluate the failure mechanism of deteriorated concrete structures with rebar corrosion using suitable non-destructive technique. The present paper investigates monitoring of failure with rebar corrosion by means of acoustic emission technique. From the experimental study it is observed that, AE technique is effective in identifying flexural as well as corrosion behavior of RC specimens.
