Briefly (costs/duration):
normal steel rebar=1
epoxy coated rebar=1.1-1.3 <- terrible in practice
zinc coated rebar=1.2-1.4 <- good
stainless steel rebar=3-4-5 <- very, very good
carbon fiber rebar=? <- AFAIK not used in new buildings, as it has a series of issues in practice, used in some rare cases of consolidation/repair of old buildings, mostly not as rebar but rather as mesh/net.
What is used, not as "main" reinforcement but to have a (much better) mass strength are fibers, they can be either steel or plastic.
- Sankozi 5y agoI think I do not understand the numbers. You wrote "costs/duration" so higher the number the worse solution (bigger costs or worse durability), yet the descriptions suggests otherwise.
- jaclaz 5y agoSorry, numbers are cost only (1 is "normal" rebar steel) order and text are duration ("normal" steel no text, base duration, the terrible in practice means that it doesn't offer longer duration, and may have issues in adherence to concrete). Not so surprisingly the higher the cost the longer the duration.
