    ABSTRACT
  • Despite two centuries of engineering success, concrete still lacks a unified scientific theory. The failure of concrete is often traced to the interfacial transition zone (ITZ), a region that governs the mechanical behaviour of concrete yet whose own properties remain incompletely understood. We identify three fundamental dependencies, namely orientation, time, and scale, that should be resolved to establish an interface mechanics in concrete.
