Geopolymer is an alternative binder to Portland cement. In this paper, nano-TiO₂ was incorporated into a metakaolin-based geopolymer matrix to impart photocatalytic properties into the binder. The self-cleaning performance of the resulting binders was revealed under UV and direct sunlight irradiatio...
