Corrosion Propagation Phase Studies on Finnish Reinforced Concrete Facades

Köliö, Arto / Honkanen, Mari / Lahdensivu, Jukka

Abstract This work discusses a research project on active corrosion as a part of the service life of concrete facade panels in Nordic climate. The objective of the studies was to contribute to the knowledge on the corrosion propagation phase in these structures under actual long term weather exposure and to generate data for its modelling purposes. The project combined statistical analysis of a large database of condition investigation data to the more in-depth analysis of twelve case buildings and field measurement data on reinforcement corrosion. Corrosion rate was tied to long term weather data representing the geographical location of the buildings. As one of the results it was shown that, although carbonation resistance remains as the primary factor in ensuring proper service life, the modelling of active corrosion may provide a considerable extension to it.
