Wood-induced corrosion on steel plates embedded in concrete

| 2025:1123 | Jonas Engblom, Bertil Sandberg, Johan Ahlström
The issue of wood-induced corrosion on concrete embedded steel plates is important for nuclear power plants, as it can potentially lead to structural integrity problems. This laboratory study aimed to investigate initiation and short-term development of this specific type of corrosion. The report is only available in Swedish with an English summary.

The results demonstrate that given the existence of a few critical factors such as connection to external cathodic surfaces, large volume of wood and high moisture in the wood piece, corrosion can be initiated on concrete embedded steel plates. Further studies are suggested to follow if and how an initiated corrosion process develops over time.
