not using old railroad rails as seen in picture 421


pretty interesting book there warning about rebar because there is no current experience (1901) if rebar will last more than 50 or 100 years so in monumental buildings that should last more than centuries rebar shouldn't be used.

i am wondering if they would classify a 6line autobahn bridge monumental because they have to be torn down after 50years because the re-bar explodes the concrete.
