Abstract:

The SLABS model of curing concrete bridge decks was developed with new boundary condition parameterizations that can accurately account for a wide variety of atmospheric conditions, addressing limitations of previous studies. Equivalent ages were estimated from the temperature predictions of SLABS and can vary up to 40 h over conditions simulated after 24 h of hydration. Depth variations of equivalent ages reach 15 h.
