Remember also the slab is going to be wet at least once a day when they wash the trucks. As it cracks, that water will get into the space between the slabs, what will that do for the cork?
tear it out and design a proper slab.
From where i am at, its about 8-10 psf dl, and about 20 psf ll. It all depends on the spec for the roofing type, additional dead load. the live load is usually snow load, or min live load.
Check IBC
Have them form a shear key at the top of the first pour, a simple 2x4 usually suffices.
I bet this happens more than you know, the contractor just doenst call about it
This is actually for a precaster. he is looking for reasons not to pour it 2", he knows its not the best idea. I think it will come down to here is what can happen, do you still want to use a 2" panel.
Any thoughts on a 2" thin cladding panel? Panel will be about 7'-0" x 4'-0" spanning horizontal. My worries are rebar shadowing, and also spalling. Granted they will be vertical, but the bars will only have 3/4" cover.
per ACI I can do 3/4" cover on a precast wall.
Im iffy about going so thin.
I had a post some time ago sort along these lines. Just design and state the bearing pressure you need. That puts it back on the owner/contractor to verify, not just also assume. If they dont, they get what they pay for.
Too many owners just want a finished product, but not pay for anything. I...
Anyone know if ASSHTO allows rebar to be field bent as needed if it has a conflict? I have some bars protruding and need to bend them out of the way a bit.
