Rezumat: Durability and service life in civil engineering are largely related to the corrosion-related phenomena affecting the steel reinforcement. Damage initiation and/or the development of structural properties start on nano/micro level. Therefore, modification of the material structure on these levels is more comprehensive study on novel approaches for corrosion control in reinforced concrete and includes investigation on the influence of tailored nano/micro range polymeric aggregates on material properties of both steel and concrete. The mechanisms related to corrosion and corrosion control are hereby discussed in terms of the possibility for establishing a durable and sustainable solution i.e. self-healing mechanisms in reinforced concrete by using polymeric micelles, vesicles or hybrid aggregates. The feasibility of self-healing is briefly presented via preliminary tests in model liquid environment. Additionally, the significant impact of minimal concentrations of nano-aggregates on global properties of the cementitious bulk matrix is also discussed.
