o:1792 Detekcija oštećenja betona na bazi propagacije ultrazvučnih talasa za potrebe ocene stanja betonskih elemenata mostova Detection of concrete damage based on ultrasonic wave propagation for assessment of concrete bridge elements condition: doctoral dissertation : doctoral dissertation sr During the exploitation period, the properties of reinforced concrete in structures constantly decrease, resulting in damage that directly affects serviceability of the structures. Initiation and development of damage are time-dependent phenomena accompanied by deteriorating processes, which are differently implied depending on the environment. The influence of environment is an important factor that determines type of damage and mode of propagation, and damage level depands on the exposure of structures elementsto aggresive action.
