Additional strategies and protective measures
Pages 22

For all major concrete infrastructures, a service period of 100 years or more should normally be required before the probability of corrosion exceeds 10%. However, since the calculations of corrosion probability gradually become less reliable for increasing service periods beyond 100 years, as discussed in Chapter  4, the corrosion probability should be kept as low as possible, not exceeding 10% for a service period of up to 150 years, but in addition, some special protective measures should also preferably be applied. Since any calculations of corrosion probability for service periods of more than 150 years are no longer considered valid, the corrosion probability for such long service periods should still be kept as low as possible, not exceeding 10% for a 150-year service period, but in addition, some special protective measures should always be applied in order to further increase and ensure the durability.
