The paper presents the results of investigations on the in-service behavior of concrete structures used in fruit and vegetable processing facilities, where environmental conditions are characterized by high chemical and biological aggressiveness. In such environments, concrete surfaces are continuously or periodically exposed to liquid media containing organic acids and microorganisms, as well as to significant variations in temperature and humidity. These factors lead to accelerated degradation processes, manifes...

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...
