Self-healing approaches for the preventive repair of concrete structures: SARCOS COST Action

The SARCOS Action is focused on the preventive repair concept, with the objective of sealing small cracks at the earliest stage of damage, both for new and existing structures, and on looking for standardized methodologies to evaluate the mechanical and durability performance of the treated structures, with continuous feedback from the modelling of self-healing mechanisms. The present contribution aims to give a general vision on the advances achieved within the SARCOS Action, including the revision of the state-of-the-art of the different aspects addressed within the Action: self-healing approaches, techniques for characterizing self-healing performance and self-healing mechanism modelling.
