Hi everyone
I am in the process of designing a slab on ground for a new freezer. The construction is of the usual type, concrete slab on 4" rigid insulation, etc...
I have calculated the thickness of the slab, using the charts found in the Ringo and Anderson book for post loads. It gives me a thickness of 9 inches.
My question is about reinforcement. The calculation that I have done assume there is no reinforcement at all. But I want to prevent curling and cracking as much as possible.
Since our client doesn't want to use fibers, my first idea was to put reinforcement 2" from the top of the slab (#4 @ 12"" c/c both ways) but I am afraid of "alligator cracks". Also, I plan to put saw cuts at 15 feet apart maximum.
Am I in the right direction?
