Concrete ('opus cementitium') was already described by Vitruvius (~80-15BC), while the modern concrete was first important after the portland cement-binder could be produced in a continuous industrial process by the use of a tube furnace, from ca. 1860. Since then production has been optimized and today's concrete is much stronger and better, in many ways. Nevertheless, the history of portland cement-concrete is not much longer than a half century, while some important constructions to be built to last 200 years, some even 300 years. What factors affect the structure's lifetime, how can these be examined, and what knowledge needs must be covered to be able to satisfy modern society's needs and requirements?
