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.
