Development of water-repellent cement mortar using silane enriched with nanomaterials

•TiO2 was successfully synthesized by bio-template synthesis method.•PFDTS-enriched with nanomaterials (TiO2 and SiO2) was developed as a superhydrophobic surface on cement mortar.•PFDTS-enriched-nanomaterial exhibit superhydrophobic surface with UV-shielding ability.•The water-contact angles of coated and admixed cement mortar were 162.3° and 162.0° respectively.•The PFDTS-enriched-nanomaterial has better freeze-thawing barrier performance than normal cement mortar.
