| | Summary: |
| | The phenomenon of dirty facades and elements of infrastructural facilities such as roads and bridges is becoming more prominent with the increase of industrial air pollution, which has a detrimental effect on the quality of urban environment and structural life cycle cost. New construction material called photocatalytic concrete is selfcleaning, and in addition it is a filter for air pollution and it is used for construction of the aforementioned structures. Self-cleaning is a result of the capacity of photocatalytic concrete enabling the façades, bridges, roads and other structures to retain their color in time, and appear as new for decades. The primary catalytic ingredient of photocatalytic concrete is Titanium oxide (TiO2), a white pigment. When activated by the energy in sunlight, TiO2 creates a charge separation of electrons which disperses on the photocatalytic surface and reacts with external substances, decomposing organic compounds. Photocatalytic concrete reflects much of the sun's heat which reduces the heat gain of the structural surfaces during the summer seasons, reduces the air temperature in urban environments, and as a result, reduces the amount of smog. The paper presents the properties of photocatalytic cement, concrete and advantages of its usage as environment friendly material and its application on important structures in the world. |
