RE: Minimum steel in slabs on ground

[Subject Prev][Subject Next][Thread Prev][Thread Next]
While I agree that ACI 318 does not specifically apply to slabs on ground by
definition, the provisions of ACI 318 still represent a standard of care
when it comes to protection of reinforcement against corrosion. If no ACI
standard applies to rebar in a slab on grade, does that make it acceptable
to place the steel 1/4" from the soil? Engineers must use their judgment in
determining when to exceed the minimum code requirements for design of a
structure; similarly, judgment must be used as to when to apply code
provisions to other structures even though not explicitly covered by the
