Abstract:

Concrete bridge decks in South Dakota have reduced services lives due to shrinkage cracking. This study evaluated the effects of varying concrete mix design parameters on shrinkage performance. Tested mix design changes include aggregate type (limestone and quartzite) and gradations (ASTM C33, Tarantula Curve, and 0.45 Power Curve), supplementary cementitious materials (fly ash), cementitious content, water-to-cementitious ratio, internal curing using saturated lightweight aggregates (expanded shale), and shrinkage reducing admixtures. These changes were evaluated for their effect on the shrinkage of paste, mortar, and concrete as measured by ASTM C1698 (autogenous shrinkage), ASTM C157 (drying shrinkage), and ASTM C1581 (restrained drying shrinkage).
