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.

Abstract: The present invention relates to a construction chemical composition comprising Portland cement, a water retention agent, a dispersing agent, and a hardening accelerator comprising calcium-silicate-hydrate, as well as a mortar composition containing said construction chemical composition. Although the composition is based on Portland cement it has a pull-off strength after 6 h meeting the DIN requirements and can therefore be used as a fast setting tile mortar.
