Does salt hurt concrete?

How does salt ruin concrete?

* Salt is a mild acid and lowers the pH in the concrete. The acidic reaction attacks the concrete paste and aggregate, weakening the structure and strength of the concrete. It also increases the pore size, allowing additional water and chemicals into the concrete, which can exacerbate freeze/thaw cycle damage.

What salt is OK for concrete?

Is it better to put ice melt down before it snows?

Ice melt should be applied before precipitation freezes or immediately after clearing snow. Shoveling the slush layer from walkways after the ice melt has done its job helps reduce concrete damage from water absorption and excess thaw/refreeze cycles.
