* Salt accelerates carbonation, a process that slowly reduces the pH levels in concrete through contact with Carbon Dioxide (air) and contributes to the corrosion of reinforcing steel. Most salts are neutral to mildly acidic (pH of 4.5 –7), and absorption of the salts (brine) by the concrete will accelerate the pH reduction of the concrete.
