FACTORS AFFECTING THE DURABILITY OF CONCRETE BRIDGE DECKS: SHRINKAGE COMPENSATED CEMENT CONCRETE IN BRIDGE DECKS- INTERIM REPORT NO. 5

Four concrete bridge decks were constructed using shrinkage compensated cement. These decks were compared to similar bridge decks of parallel structures constructed using Type II Portland cement. Instruments were installed in both sets of bridge decks. Internal stresses and length changes were measured and compared. Deck cracking was plotted and compared by numeration. It was determined that shrinkage compensated cement had some effect in reducing deck cracks. The study confirmed previous studies (Factors Affecting the Durability of Concrete Decks-Interim Reports 1 and 2 - Construction Practices) that weather, competence of workmen, and early curing have the greatest effect on deck cracking. It was concluded that the demonstrated effect of shrinkage compensated cement was not great enough to make its use worthwhile on bridges in California.
