Abstract:
The purpose of this paper is to sumarize and report the results of field installations of Type K shrinkage-compensating concrete in bridge decks in Ohio. Typical examples concerning methods of placement, finishing, and mix designs are presented as well as the results of these procedures. Long-term results in the form of field inspections and half-cell potential readings are presented. Specifications and cost data are also included. The conclusion is drawn that the use of shrinkage-compensating concrete as a bridge deck material will reduce the instance of cracking and, consequently, reduce reinforcing steel corrosion which, in the opinion of the writer, is the major cause of bridge deck failure.
