Bright and slip-proof engineered cementitious composites with visible light activated photo-catalysis property for pavement in tunnels

Pavement in tunnels requires specific properties and functions. In this study, bright and slip-proof Engineered Cementitious Composites (ECCs) with visible light activated photo-catalysis properties are developed for pavement applications in tunnels. A carbon-modified TiO2 is used to engage a visibl...
