Abstract

The present work addresses the aggregation/dispersion properties of two commercial titanias for application as photocatalysts in concrete technology. A microsized m ‐TiO 2 (average particle size 153.7 ± 48.1 nm) and a nanosized n ‐TiO 2 (average particle size 18.4 ± 5.0 nm) have been tested in diffe...
