Characterization of Bioconcrete and the Properties for Self-Healing
Résumé
Concrete is the most widely used material in the world. It is a material with several advantages such as cost, ease of execution, adaptation to different shapes, satisfactory resistance to atmospheric effects, thermal and mechanical resistance, and extended life span. Therefore, the quest for its improvement is constant. Despite all these advantages, it presents a pathological manifestation intrinsic to the material itself-the appearance of cracks-which, depending on the cause, generates very high maintenance and conservation costs and can compromise the entire structure. Despite all preventive measures, it is not always possible to avoid the appearance of this pathology, which tends to intensify the constant search for greater use of its resistance. To remedy this problem, a Dutch microbiologist has developed a bio-based self-regenerating concrete that can not only reduce the need and, consequently, costs for maintenance of the concrete structure, but also increase its durability.
