“…When bacteria are used to heal cracks in cementitious materials, the crystal growth and crack width reduction can be monitored in time by using microscopic analysis . Also when crystalline admixtures, expansive agents, autogenous healing, promoted and stimulated autogenous healing with SAPs, microcapsules with bacteria and other healing agents, the combination of bacteria and SAPs, and sodium‐silicate saturated lightweight aggregates are studied, microscopic analysis can be used.…”

“…A self‐healing process can be defined as an autonomous (or with limited human intervention) in situ repair of damage occurring to materials. Up to a certain extent, some building materials own a natural self‐healing capacity, which contributes to their durability . The natural self‐healing ability of building materials such as lime mortar, cementitious materials, and even natural stone is related to fluid flow migration .…”

“…The most common fibers used are steel, glass, asbestos, Polypropylene etc. When the loads imposed on the concrete approach failure, crack will propagate, sometimes rapidly; fibers in concrete provide a means of arresting the crack growth …”

“…Por otra parte, cuando en la matriz cementicia se añaden adiciones especialmente diseñadas para promover la autorreparación del material cementicio [4], como por ejemplo los aditivos cristalinos [5,6], el proceso se denomina "autorreparación ingenierizada" (engineered healing, en inglés). A su vez, la sinergia entre los materiales cementicios reforzados con fibras y las técnicas de autorreparación (self-healing) están dando lugar a soluciones con un gran potencial [4] ya que las fibras pueden mejorar el proceso de autorreparación debido a su capacidad para restringir el ancho de las fisuras y aumentar la formación de fisuración múltiple [1, 6,[8][9][10]. Se ha comprobado que fisuras con un ancho menor a 30μm se autorrepararon completamente y, en algunos casos incluso fisuras con un ancho de 50μm [2].…”
