How many yards does it take for a slab 24' long x 16' wide x 6 inches thick? This is a driveway.
In addition, what strength of concrete is the best to use? Do you put wire mesh in the concrete for stability and to limit cracking? Is it best to put down a gravel base (washed gravel or road base) mix before laying the cement? Lastly, how large a piece can be laid at once if you put in an expansion joint strip at 12' (say 2 slabs 16' wide with a crack seam at 8' x 12' long)? We want to do it right and it is a self-do project. Thank you.
