Is there main difference of concrete mix between column and wall? or there exists no difference between two in mix.

RE: concrete mix

Not really. You have to look at placement constraints, strength requirements, exposure, and durability.  Most vertical placements have consolidation issues.  Make sure the mix design accommodates the geometry of the placement...for instance, if you have rebar with a cover of 1-inch, you want to make sure that your aggregate in the mix is not too large to achieve that with good consolidation. Then you have to balance the coarse aggregate size with the amount of cement necessary to achieve the strength you need. Not as easy as it looks!

Thanks, Ron.
That's what I thought.
