Life Cycle Assessment (LCA) of Microcapsule based self-healing in concrete

Self-healing technologies provide the long-term resilience of concrete structures by enabling self-diagnose and self-repair damages (aging cracks, cyclic load damages, corrosion-induced cracks). However, self-healing require special additives materials in addition to ones conventional concrete. Hence, it is often perceived have higher environmental impacts, therefore, necessary understand same. This study aimed analyse life cycle assessment (LCA) with microcapsules produced different techniques investigate sustainability these concretes. Two microcapsule techniques, namely complex coacervation membrane emulsification, were studied at laboratory scale then projected industrial scale. The analysis shows that does not adversely impact emissions production stage if supplementary cementitious are used. Further, beneficial effects considered use phase, impacts much lower. Thus, this gives meaningful insights identifying major helps improve their design application
