Effects of Salt on Concrete - Concrete, Sand, Stone ...

Order concrete at 4,000 psi or greater. Use of a water reducer in the mix will minimize water in the mix (stronger concrete), yet maintain flowability (keep it easy and cheap to place). Excessive water will lower the strength of the concrete and if that water becomes trapped it could also have additional weakening effects on the surface.
