BEHAVIOR OF SHRINKAGE-COMPESATING CONCRETES SUITABLE FOR USE IN BRIDGE DECKS. INTERIM REPORT-PHASE II

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 concrete decks sections were 8 in. (200 mm) thick, 2 ft (610 mm) wide and 4 ft (1220 mm) long. The composite section was 8 in. (200 mm) thick, 3 ft (910 mm) wide and 6 ft (1830 mm) long. The reinforcement was typical of that used in bridge decks in Illinois. 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. /FHWA/
