Behavior of Shrinkage-Compensating Concretes Suitable for Use in Bridge Decks
The objective of the research reported here was to determine the expansion and shrinkage behavior of full depth concrete bridge deck sections, composite and non-composite, cast with shrinkage-compensating cement concrete. The specimens were stored at temperatures of 38 F (3.3 C), 70 F (20 C), 100 F (38 C) and one specimen was stored outside. All specimens were cured 7 days under wet burlap. The results indicate that residual compressive stresses can exist in the concrete after 120 days when appropriate restraint, appropriate shrinkage-compensating cements, and adequate curing are used.
