| description | Among the various possibilities to tackle the issue of concrete damage within its structural service life, the biomimetic approach has favoured the development of innovative solutions such as the use of 3D printed vascular networks suitably incorporated into concrete structural elements to inject and convey the most suitable healing agent upon crack occurrence. These systems, able to cope with damage of different intensities, may lead to improvements of the structure’s durability, through the closure of cracks, and a consequent reduction of the frequency of major maintenance activities. The present work investigates the environmental sustainability of the aforesaid self-healing technology through a Life Cycle Assessment (LCA) analysis. The attention has been also focused on the 3D printing process of the network due to the key role that it could play, in terms of environmental burdens, when upscaled to real-life size applications. The case study of a beam healed by means of polyurethane injected through the network and exposed to a chloride environment is reported to better predict the potential improvements in terms of overall durability and consequent sustainability within the pre-defined service life. |
