Abstract
Concrete is the most used material in the field of Civil Engineering, due to the considerable flexibility that it offers in design, and also due to its low cost. On the other hand, because of its reduced tensile strength, it is also one of the most prone to cracking materials. For this reason, solutions for damage management have been developed in recent years. However, current researches point to sustainable treatments, both in ecological and economic terms. Therefore, self-healing cement-based materials have been targeted, through the use of different strategies including nonencapsulated and encapsulated technologies, to be embedded inside the matrix during the casting phase.
Nowadays, norms or guidelines that regulate their use do not exist so solutions to be used must be sought in relation to various factors such as capsule/sealant/matrix compatibility, environmental conditions, expected extent of damage and so on
