ECLIPS WORKSHOP IN BRUSSELS, MARCH 23, 2017
Enhancing Concrete Life in Infrastructure through Phase-Change Systems (ECLIPS), advances a transformational concept based on incorporating climate, and application-specific phase-change materials (PCMs) into concrete to for increased durability and lifespan of new road infrastructure.
The ability to incorporate PCMs into the concrete matrix has implications on enhancing a range of material-and-structural performance descriptors. The intelligent (i.e., temperature-sensitive) storage or release of thermal energy by PCMs provides an adaptive capability to concrete, when embedded with PCMs, to regulate its internal thermal environment. This proposal, ECLIPS, builds on the ability of custom PCMs to:
- limit temperature rise and associated early-age deformations in concrete to reduce the risk of thermal cracking
- restrict the magnitude of diurnal-or-seasonal temperature variations and deformations of restrained concrete elements over long time scales to limit damage due to thermal fatigue
- provide self-thawing/warming capabilities to concrete thereby rendering concrete more resistant to freeze-thaw action, and related damage
