Abstract:

The Oregon Department of Transportation investigated periodic bridge washing as a way to possibly remove chloride from the concrete and stop further uptake of chloride ions. Washing trials were conducted over a 4-year period on concrete blocks to determine whether chloride ions can be removed from the concrete or at least prevented from entering the concrete. The results showed that washing did not reduce the chloride content once the chloride had defused into the concrete, but washing once a day with 11 liters of fresh water per square meter reduced the uptake of chloride ions by 86%. Washing once per month reduced the uptake of chloride ions by only 5%.
