Abstract

In recent years, self-cleaning concretes have gained significant importance due to their high capacity for reducing environmental pollution and maintenance costs. These concretes, employing photocatalytic coatings with titanium dioxide (TiO₂), facilitate the removal of pollutants and help maintain the beauty and cleanliness of urban facades. However, the durability and sustainability of self-cleaning concretes against chloride ion penetration, particularly in corrosive environments, remain ambiguous concerning their widespread application. This study aims to investigate the effect of TiO₂ on enhancing concrete durability against chloride ion penetration and its self-cleaning properties. For this purpose, five concrete mix designs with titanium dioxide at varying percentages of 0, 5, 10, 15, and 20% by cement weight were prepared and evaluated using the RCMT method in accordance with Section 9 of the National Building Regulations. The results demonstrated that adding up to 20% TiO₂ resulted in an 80% reduction in chloride ion penetration compared to the control sample. Furthermore, the self-cleaning properties were significantly improved in samples with 15% and 20% additive. This research indicates that utilizing titanium dioxide in concrete not only enhances durability in corrosive environments but also enables the production of self-cleaning concretes suitable for use in urban pavements and structures.
