Abstract
The environmental sustainability and sustainability of materials worldwide is the most concerning topic in the
selection process of materials for construction. Self-Cleaning Concrete (SCC) consists of self-cleaning qualities and it is an
environmentally friendly material. The main advantage of this new, modern composite helps in reducing maintenance costs
along with a clean environment. This modern concrete removes dust and pollutants under UV rays of sunlight by
photocatalytic action. In this study, M40 grade concrete was prepared conventionally and by the addition of Titanium
dioxide (TiO2). TiO2 is added to concrete in amounts ranging from 0.5%, 1.0%, and 1.5% of the weight of cement. The
compressive strength and flexural strength of concrete specimens of size 150mm X150mm X 150mm and 100mm X
100mm X 500mm respectively. Then the specimens were cured and tested for 7 and 28 days. The self-cleaning ability of
SCC is investigated using methyl orange, methylene blue, and Spectrophotometer under UV light or sunlight.
