One Year, and cure and seal the slab too, this makes a big difference.
Good Luck!

There are a few things you should do when placing concrete for a salt shed. Consult the ready mix supplier about admixtures that whan added to the mix will make the concrete less vulnerable to chloride attack. Low water to cement ratio, corrosion inhibitor in reference to the steel reinforcing, silica fume added to the mix, in my opinion, is the way to go. Its a little more costly, but well worth it. As stated above, it must be cured properly.

Waiting a year and relying on sealers which have to be replaced periodically seems unnecessary when there are concretes which are totally un-impacted by salt.
Iagree with all of the input so far, I just would further submit that there are types of concrete which do not have the foibles portland based concrete does.
