Abstract |
|
Air pollution is an environmental problem that has significant negative health implications for humans as well as other living organisms. Major primary pollutants that are produced by human activity include nitrogen oxides (NOx), sulphur dioxide and volatile organic compounds (VOCs) which are emitted from combustion at high temperatures. When photocatalytic materials absorb ultraviolet radiations from the sun, hydroxyl radicals and superoxide anions are created that have the ability to react with pollutant molecules such as NOx, SOx, thus converting to less harmful substances. In this paper properties of concrete such as Grade of concrete is M25, W/C ratio is 0.45, Tio2+OPC=3.5:96.5 has been taken.After one day of curing all samples were coated with RhB (Rhodomine dye) solution on top side and oobservations of the reduce the dye is measured between different time intervals. |
