Investigation of Self Cleaning Concrete by Using Titanium Di-Oxide

Concrete is the most extensively used construction materials for building technology. But, cement production releases high amounts of carbon dioxide (CO2) to the atmosphere that leads to increasing the worldwide or global warming. Thus, another, environmental friendly construction material such as photocatalyst concrete has been developed. Photocatalytic concrete applies greener alternative binder, which is a modern-day construction material that replaces the Conventional cement. This technology presented nano particles such as nanoclay into the cement paste in order to improve their mechanical properties. The concrete materials also have been developed to be performed as self-cleaning construction materials. The self-cleaning properties of the concrete are induced with the help of photocatalytic materials such as titanium Di-oxide (TiO2). Self-cleaning concrete that contains those photocatalytics will be energized by ultraviolet (UV) radiation and quickens the decomposition of organic particulates. Thus, the spotlessness of the building surfaces can be maintained and the air surrounding air pollution can be reduced. This paper briefly reviews about self-cleaning concrete.
