Indian Concrete Journal - ICJSummary: As we know that mostly pollution comes from the industry and the vehicles have badly affected the aesthetic view of structures. Cement manufacturing mainly emit much CO2 (carbon dioxide) into the atmosphere, contributing to global warming. Because of climatic changes caused due to global warming, innovative concepts are needed to control the performance measures of sustainability, stability, and safety to the development of civil engineering. Nanotechnology is an essential method for increasing the durability of cement-based products. This study reviews the problem, challenges and benefits of selfcleaning construction materials. Recently researches based on self cleaning materials have provided option for traditional concrete use. Researchers conducted numerous investigations regarding self-cleaning concretes. Self-cleaning concrete would be a viable option for creating a cleaner environment that contributes towards sustainability and environmental protection. The incorporation of photo catalytic elements like zinc oxide (ZnO) and titanium (TiO2) induces the concrete’s self-cleaning characteristics. First the photo catalysts in self-cleaning concrete are powered by ultraviolet (UV) radiation, Secondly, photo induced hydrophilicity makes it look clean, the pollutant is organic and causes dirt over the surface, It is easily removed by rain fall or manual rinsing. As a result, the integrity of buildings could be sustained, and air pollution in the surrounding area could be reduced. It is concluded that Bi2O2CO3 photo catalyst gives better result in self cleaning than TiO2
