Your two comments;

and
"Oh, for heaven's sake. Haven't you ever heard of rebar?"
imply that you equated an engine block dumped in a hole in the ground,
with engineered and correctly installed reinforced concrete. ?I took
exception to that.

I appreciate that you think the OP - a guy who wants to toss a
considerable quantity of scrap iron into a set of steps as filler - as
being so clued in to the correct amount of concrete coverage, and
would know how to suspend an engine block to insure that amount of
coverage. ?I have no such illusions.

ideally all rebar should be non magnetic stainless, which never

rusts...........

I'm late to the party but if they are really concerned about corrosion in
the rebar maybe they should look into getting some of the (fairly) new stuff
called MMFX rebar. It is five times as corrosion-resistant and up to three
times as strong as conventional steel. He could use less steel and it would
last longer than just about any other comparable product. Ameristeel is
advertising a product called "Z-Bar" that is better (per their claim, not
mine) than just plain epoxy coated bars, but I have not *been involved with
any project that used this material, so I can't say anything one way or the
other about it.

Whats the green rebar I saw a while back, was it a coating?
