Evaluation of the self-healing effect in cement-based materials with embedded cementitious capsules by means of Acoustic Emission techniques

Due to its low tensile strength and the presence of defects brought on by improper construction methods or other factors, cracks in concrete are practically inevitable. For reinforced-concrete structures, even if do not necessarily increase risk collapse, they unquestionably hinder aspects such as service life. Self-healing cementitious materials have been developed because growing concern for security sustainability structures. these new be used actual it is essential conduct research into self-repair effect that may offer, possibly quantify directly on-site, means non-destructive methods. In this sense, objective work use Acoustic Emission (AE) analyses non-destructively characterise response an autonomic capsule-based system, a function specific polymeric healing agents contained capsules. Comparisons will made between reference selfhealing specimens, different self-healing specimens themselves, through analysis parameters ultimate load, absorbed fracture energy, emitted energy. Such type can give valuable insights only quantitative but also qualitative (such level brittleness ductility introduced system adopted) view possible applications real
