It generally takes several years for new technologies to come onto the market in the building sector, not just on account of the development work and performance verification procedures required, but also because of the legal aspects to be considered. The aim of the C³ CarbonSpeed project was to create a guideline to complement the existing verification procedures of the building authorities (approval in individual cases, national technical approval) with a view to shortening the time required for the introduction of solutions with carbon concrete.
Performance-related approaches for the assessment of new product developments are being discussed in European Standardisation committees working on updated versions of the Eurocodes and standards for concrete technology. Similar approaches are being considered by the building authorities (German Institute for Building Technology, DIBt) and the European Organisation for Technical Assessment (EOTA). In the course of the project, these approaches were to be applied to carbon concrete and the feasibility of their implementation discussed with the decision-makers of the building authorities.
