I have an 8" cmu, 2-hr, masonry bearing, stair shaft wall. At each floor a steel beam bears on a bearing plate on the wall supporting hollow core precast plank. The beam stops 1" from the inside face of wall & the mason is planning to fill it in with mortar and/or maybe a soap block. Does this compromise the 2-hr rating?
