AN EXPERIMENTAL INVESTIGATION OF PHOTOCATALYTIC CONCRETE

Abstract

Most of the cities around the world struggle with increasing of car exhaust fumes, Industrial smog and other forms
of Air pollution. It can produce negative health implications for Humans as well as other living Organisms. The major
primary pollutants are produced by the human activities. That are NOx, SOx and VOCx which are emitted from high
temperature. Photocatalytic materials (TiO2) are absorbing the UV rays from the Sun, and then Hydroxyl radicals and the
Superoxide anions are created. It will have the ability to react with air pollutants such as NOx and SOx, thus converting to
less harmful substances. It involve depolluting the environment automatically. In this project we are using M30 grade of
concrete. Cement is to be replaced by TiO2 for 0%, 3%, 4% and 5%.
