Early Age Properties of Internally Cured Concrete for Pavement and Bridge Decks

Presented By: Jose Pacheco, MJ2 Consulting, PLLC Volumetric changes in concrete bridge decks and pavements can often result in cracking or warping, leading to reduced performance and durability. Volumetric changes in concrete are caused by changes in the moisture content of hardened concrete or the self-desiccation of cementitious materials with a relatively low water-to-cementitious materials ratio (w/cm). The main objectives of this research project were: to evaluate different materials available for internal curing for use in internally cured concrete, evaluate the performance of fresh and hardened concrete with and without internal curing, and determine the potential impact of using internally cured concrete on the concrete durability and sustainability of bridge deck and pavement placements.
