Cement-based construction materials, such as mortars and concretes, are frequently exposed to aggressive environments containing chloride and sulfate ions, leading to corrosion processes that significantly affect their durability and structural performance. In many cases, these degradation phenomena are intensified in industrial environments or coastal areas, where the concentration of aggressive agents is higher. In recent years, the use of nanoparticles as functional additives in cementitious materials has gaine...

In the context of sustainable development and the urgent need to reduce the environmental footprint of the construction industry, the reuse of recycled concrete waste in mortar formulations has emerged as a promising strategy. However, the incorporation of such waste materials typically leads to diminished mechanical performance, primarily due to the reduced chemical activity of the recycled aggregates. To address this drawback, nanoparticles have gained attention as functional additives capable of restoring or ev...
