The Effect of Climate Change on Freeze-Thaw Cycles in Nordic Climate
In Finland weather conditions are very aggressive for concrete structures which are not sheltered against rain. One of the most serious issues concerns freeze-thaw cycles when at the same time ambient conditions are wet. This situation is common in Finland during autumn, spring and warm winter when daytime temperature is slightly above 0 °C and by night below.
Based on earlier studies the number of freeze-thaw cycles is slightly higher inland than in Southern Finland and coastal areas but the higher amount of rain and sleet in coastal areas makes the number of freeze-thaw cycles needed for the same degree of frost damage much lower. This paper studies how the change of freeze-thaw cycle occurrence affects durability of concrete structures. The study utilizes also models the Finnish Meteorological Institute (FMI) has developed for climate change effects on critical climatic conditions based on three IPCC (2007) scenarios for the evolution of greenhouse gas.
