Proposed Testing of Concrete Sealers
Chlorides, in sufficient concentrations, will cause corrosion of steel reinforcement in bridge decks. Previous studies have shown that de-icing chemicals and practices used by the Kentucky Transportation Cabinet (KYTC) can result in problematic levels of chloride at steel reinforcing depths in a relatively short amount of time. With the advent of liquid applied pre-treatment deicing chemicals testing performed in Kentucky indicate chloride levels in bridge decks at a depth of two inches have increased significantly. The action levels for chlorides in concrete as related to reinforcing steel corrosion are: (1) Corrosion will initiate at 0.03% chlorides by weight of concrete. (2) Accelerated corrosion begins at 0.08% chlorides by weight of concrete. (3) Major section loss of steel occurs at 0.18% chlorides by weight of concrete.
