Abstract
Designing concrete structures for a very long service life may have considerable economic and societ
al benefits including
minimized material co
nsumption over the long term
,
thus contribute to more sustainable solutions. However, such long service
lives require determination and extrapolation of environmental loadings and material durability perf
ormance over a long perio
d,
as well as reliable and
operational models for service life predictions.
C
odes and standards give deem

satisfied
recommendations for intended working (service) life up to
about
100 years.
However, i
f
higher
working lives

specified
, as for monumental bu
ildings, bridges and oth
er important infrastructures,
more in

are
required
.
