1. Rapid urbanization and industrial development have led to increased environmental pollution, resulting in the accumulation of dust, organic contaminants, and harmful gaseous pollutants on concrete surfaces. These contaminants adversely affect the aesthetic appearance, durability, and maintenance requirements of civil infrastructure. To address these challenges, the development of sustainable and multifunctional construction materials has gained significant attention. This study investigates the influence of SRL grade Titanium Dioxide (TiO?) on the photocatalytic, self-cleaning, and mechanical properties of cement mortar. 2. In the present experimental investigation, cement mortar specimens were prepared by partially replacing cement with varying percentages of SRL grade TiO? while maintaining a constant cement-to-sand ratio of 1:3. The specimens were cast in standard cube moulds and cured for periods of 7 and 28 days. The performance of TiO?-modified mortar was evaluated through compressive strength testing, photocatalytic dye degradation assessment, and self-cleaning surface observations. 3. The experimental results revealed that the incorporation of Titanium Dioxide significantly enhanced the photocatalytic activity and self-cleaning performance of cement mortar surfaces. Furthermore, an optimum dosage of TiO? contributed to a marginal improvement in compressive strength due to its micro-filler effect and its ability to promote cement hydration. However, higher TiO? contents resulted in reduced performance, primarily due to particle agglomeration and non-uniform dispersion within the mortar matrix. 4. The findings demonstrate that TiO?-modified cement mortar possesses excellent potential as an environmentally sustainable and multifunctional construction material. Its application can contribute to the development of self-cleaning building facades, air-purifying pavements, and durable infrastructure systems, thereby supporting sustainable urban development and environmental protection.
