I hired a a guy to build 40x60 barn plan called for steel rebar on 16 inch center, he used number 10 wire mesh will that handle the weight of a 100 horse tractor?What is differnce between them.Thanks
10 ga wire is what we use here for sidewalks only. The corner sections require 6 ga (bigger, thicker wire). There's zero comparison of deformed rebar and mesh. If you have a contract with specs indicating the rebar, get an attorney. There's also a MAJOR price differential between the two.
MESH
aci doesn't recommend any steel ( rebar OR mesh ) in 4" slabs due to the improbability of it being installed in the right position. mesh will add strength to the concrete while its still ' green ' but, after that, it just holds the broken pieces together & makes it harder to remove & do over correctly we thicken the slab to 5 or 6" then add rebar correctly located & spaced :yes: fiber mesh is a good item IF you own fiber mesh OR sell it - we never use it :no:
The concrete supplier that my buddy uses does use the premixed concrete that uses that suspended fiber mesh reinforcement that is inside the mix.
I am going to putting down a rigid foam layer to isolate ground temperatures (i.e. slab is above the frost line) and I want to put radiant heat in the slab for winter time working conditions. No need to condition the space in the summer.
What would you recommend in terms of reinforcement and would you recommend pouring a 6" slab instead of a 4".
There will be some heavy item in this space (car lift, multiple vehicles in the same location via stacked on the lift, etc).
The original post is written in past tense. I would assume that the slab is already down. If so, you're not in a good position as the slab is going to be weak at best and there won't be any point loads that this will stand unless it's poured on solid rock. Fibermesh, jeez, I wish I had a clue just how much of that crap I've had to jack hammer and haul off due to complete failure. It's not allowed by code here anymore. It cost the subs here tons of money in back charges. I doubt the material suppliers ever paid the subs. If you haven't poured the slab yet, assuming your plan is from an engineer, follow it to the letter. If the slab is not from an engineer, hire one or expect issues. A foundation doesn't tolerate much guesswork.
