    Sammanfattning : Microbially induced concrete deterioration has been discovered in several Norwegian subsea tunnels with significant disintegration of the calcium silicate hydrate (C-S-H) and steel fibre corrosion in areas with leakages of saline groundwater. Complex microbial biofilm activity together with abiotic attack from saline ground water, with high concentrations of Cl−, SO42−, Mg2+ and HCO3−, are responsible for the degradation in the specific subsea tunnel environment.
