Pollutant removal from paint, mortar, and reinforced composite and evaluating the engineering properties by incorporate the photocatalyst: BaTio3

Abstract

The present work explores to study the pollutant removal properties of mortar, concrete, and paint by incorporating the BaTiO3 as photocatalysts with different dosages (0.5%, 1%, and 2%) replaced by weight of cement and 20 g in white paint of 40 mL. To investigate the pollutant removal property of specimens prepared with Ordinary Portland Cement (OPC) and white cement (WC) and white paint on ordinary wall, Rhodamine B dye is used as a pollutant. The pollutant removal property was investigated for 4 days in laboratory experiment and 4 days in the field experiment. It was observed that the specimen having dosage of 2% photocatalyst have the best result in pollutant removal than the other specimen in laboratory experiment. The catalyst shows pollutant removal ability in white paint even in the presence of sunlight effectively and maintains the color’s grace of the paint. The compressive strength increased with the addition of a photocatalyst, and other engineering properties of the specimens were the same even at different dosages of the photocatalyst. The photocatalyst BaTiO3 remove the pollutant from paint, mortar, and reinforced composite without affecting the all the engineering properties.
