Nanodispersed TiO2 hydrosol modified Portland cement paste: The underlying role of hydration on self-cleaning mechanisms

The self-cleaning performance of photocatalytic cement paste is related to the dispersion of nano-TiO2 in the hardened matrix. This work aims to study the influences of Portland cement hydration on the self-cleaning behaviour of acidic anatase TiO2 hydrosol modified hardened Portland cement paste (H...
