Abstract: A process for hydrophobization of concrete or mortar using an aqueous dispersion containing an alkylketene dimer, at least one emulsifier and a condensation product of phenol sulfonic acid and formaldehyde, naphthalene sulfonic acid and formaldehyde, or naphthalene sulfonic acid, phenol, formaldehyde and urea; and the concrete or mortar obtainable by the process. The process allows effective mass and surface hydrophobization of concrete.
