A new trend in concrete technology is to introduce photocatalytic concrete, also known as a self-cleaning concrete. This technology is based on the addition of TiO2 (titanium dioxide) to concrete mixes. Photocatalytic activity of TiO2 and its hydrophilic properties make it suitable for addition to building materials, particularly in architectural concrete or self-consolidating concrete. When concrete surface is exposed to the sunlight most pollutants are neutralized. In the present study the influence of addition ...
