Evaluation of Long-Term Exposed Structures and their Maintenance

Abstract:

Corrosion rate of hot dip zinc coating exposed at atmospheric environment can be predicted according to EN ISO 9223 and EN ISO 9224. Prediction models based on dose response (D/R) functions express the effects of environmental parameters on the corrosion of material. The investigation of corrosion protection of construction exposed longer than 30 years were performed. In this paper the selected results of evaluation of galvanised infrastructures from corrosion failure and durability point of view are presented. The field data are compared to prediction models. The residual thickness of zinc coating was measured on selected profiles of the truss structures. The maintained organic coatings were applied on these constructions and there are presented results after 8 years.
