Any one know what the per sq inch lb rating for a concrete block wall is?

Have a block wall with a 14 foot(21lbs per) 10" steel beam with 2 stories loaded on it. I thought it was fine, I fiiled the 2 stretchers with mortar and rebar to each side.

A phisics professor from a local school said no way, even has my customer covinced, The SE said it's fine. To no avail. Customer wants steel post.

I know I've done this a hundred times and the deal is done and said, but I was wondering what you fellas thought.

I'm no engineer. Ask your local building inspector. I assume it has to be inspected anyways.
The building inspector is obligated to go with what the construction drawings that were stamped by the SE. If you change it - you should have the SE sign off on it.
Glass, my book is showing it as 1,000 to 3,000 P.S.I. In a habitat, I would use the lowest figure. The safety factor is not included, for humans it is usually 3 to 1. To be on the safe side, I would consider 333 P.S.I. as a maximum. Legally, you can work off of the max compression and go for 1,000 P.S.I.
I would check with the block manufacturer for their rating, it would make everything much smoother for you.
