The primary aim of RT1 is to develop and validate a suite of technologies for healing cracks in cementitious composites, suitable for a wide range of applications. The research will explore some fundamentally new ideas for achieving self-healing and bring to fruition the range of multi‐scale self-healing technologies considered in M4L, based on tailored bacterial healing systems, very high performance shape-memory polymer tendons, multi-scale vascular networks, second generation microcapsule design in order to achieve enhanced versatility for specific applications. The aims of providing a unique set of design and tailoring procedures and validating the technologies and procedures will be realised by:

  • the development of state‐of‐the‐art numerical analysis tools, design methods and optimisation procedures
  • carrying out full‐scale laboratory tests and site trials to prove the efficacy of these SH technologies. The latter will involve all Institutions and will explore the full range of technologies, their interactions and applicability.
