The EPIC2 initiative, one of the Federal Highway Administration’s (FHWA) EDC-7 innovations, investigates the implementation of Internally Cured Concrete. This emerging technology shows potential benefits such as improved project life cycle costs and enhanced sustainability when implemented in New Jersey, particularly for bridge deck applications. The process involves replacing a portion of normal fine aggregate with prewetted Lightweight Fine Aggregate (LWFA), which stores water inside fine aggregate particles. These particles are evenly distributed through the concrete matrix and slowly releases their trapped moisture during the curing process, providing a more consistent curing effect. High performance concrete (HPC) particularly benefits from this process due to its low permeability which reduces the effectiveness of conventional curing. HPC is also known for its rapid hydration and strength gain which increases sensitivity to early age cracking under restrained conditions, such as those existing in a cast in place bridge deck. This project investigates numerous internal curing materials for usage in NJDOT internally cured HPC (HPIC) and proposes methodology for implementation in New Jersey.
