    Abstract

    In Europe severe damages on reinforced structures exposed to de-icing salt cause annual costs in a range of several billion Euro. There is a considerable saving potential just by detecting the deterioration with its dimension in time and subsequently carrying out appropriate intervention before damage is visible or even occurs. The monitoring of structures enables a continuous condition assessment. By the implementation of sensors the water content within the concrete can be measured which enables to assess the proper operation of coatings and the effectiveness of hydrophobic treatment. In this context typical application examples will be given. The implementation of corrosion sensors enables to locate the depth of the depassivation front and therewith the execution of intervention measures on time before the reinforcement becomes depassivated. In this context a typical application example such as the parking garage of the Allianz-Arena in Munich will be given. Besides it will be shown how such additional information from monitoring can be used to update a service life calculation as a valuable tool for life cycle management.
