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. One of the very recent contributions to durability and sustainability of concrete is the self-cleaning ability. This effect is achieved by applying Photo catalytic materials such as titanium oxide to the concrete mix.Photocatalytic components that use the energy from ultraviolet rays to oxidize most organic and some inorganic compounds. Air pollutants that would normally result in discoloration of exposed surfaces are removed from the atmosphere by these Photo catalytic components, and their residues are washed off by rain.. Effects of pollution are visible on building exteriors throughout our cities and towns. These are also responsible for our smog covered cities and the resulting migratory smog in rural areas in addition to various health related issues to the mankind. So, this new cement can be used to produce concrete and plaster products that save on maintenance costs while they ensure a cleaner environment Hence, this paper, basically describes the role of Photo catalytic cement in production of innovative construction material termed as Photo catalytic Cement concrete or popularly called as Smog eating concrete or Self Cleaning Concrete.
