PRODUCTION OF SELF-CLEANING CEMENT USING MODIFIED TITANIUM DIOXIDE
The present work explores the applications of titanium dioxide and photocatalysis to produce self-cleaning cement. In the present study, self-cleaning cement was prepared using titanium dioxide and white cement. To enhance the performance, titanium dioxide was also doped with Ag, and further used for preparation of self-cleaning cement. The doped titanium dioxide was characterized using XRD and TEM. The surface of prepared cement samples were analyzed using SEM. The self-cleaning ability of the prepared cement samples were evaluated in a photocatalytic activity test under sun-light as well as artificial UV-light. It has been observed that prepared cement samples are able to clean their surfaces.
