Concrete is the most widely used material in civil and building engineer thanks to its highly cost-effective production and installation, compressive strength and durability properties, but one of the major problems that affects this type of material is the emergence of cracks which can impair its durability and mechanical characteristics, possibly leading to premature collapse of the structure. The research in this field is moving fast to improve the maintenance strategies, with the development of novel high-efficiency repairing products and the definition of innovative application techniques, in order to both guarantee and extend the structure lifetime and limit the need for demolition and production of new concrete, thus reducing the overall environmental impact of these activities.
