Internally-sealed Concrete for Bridge Deck Protection

Report No: 82-R19

Published in 1981

About the report:

The experimental deck exhibited a significant amount of cracks in the survey done at 29 months after heat treatment. These were attributed mainly to the heating and the cooling process, as only a few cracks were observed on the control deck. Delaminations totaling about 3% of the total deck surface were found on the experimental structure at 39 months and none were found on the control deck. Measurable but low chloride contents compared to the corrosion threshold value were determined at 42 months in the experimental deck but no significant value was obtained on the control. The electrical potential values at 47 months on the experimental deck indicate the possibility of corrosion taking place, whereas for the control the values show that at a 90% probability level no corrosion activity is occurring. The report includes recommendations on the future use of this protective system and for frequent evaluations of the experimental deck.
