Concrete is made of cement, sand, gravel and water to produce an applicable paste, which is continuously hardened over time. There was a lot of problems that occurred in concrete when the strength lost its integrity subjected to load and also a dirty concrete surface due to aggressive air pollution in crowded cities, industrial areas and/or marine structured buildings. Self-cleaning concrete using rutile titanium dioxide (TiO2) as an additive known as nanomaterial was proposed for this study. The utilisation of photocatalytic materials in concrete was able to solve the problem and also assisted to reduce and degrade air pollution under ultraviolet radiation. The main objective of this study was to determine the mechanical properties of self-cleaning concrete using rutile TiO2. TiO2 with percentages of 0.50, 1.00, 1.50, 2.00, 2.50, 3.00 and 3.50% of the total weight of the cement was used. There were two parts in the experimental activity, which included the physical and chemical of the TiO2 and the mechanical properties of the self-cleaning concrete. From the results, the self-cleaning concrete with 0.50 and 1.00% was reported to have a compressive strength value more than the control mix, approximately 0, 1.16 and 6.0%.
