Abstract
The present invention relates to liquid accelerators for the setting of concrete mixtures. These accelerators have a long shelf life even in higher concentrations than the liquid accelerators known heretofore and, within the defined concentrations, produce no precipitation. The new accelerators are characterized by containing only potassium aluminate, potassium carbonate and potassium hydroxide in a defined range. They can be used in any known hydraulic binding agents, they shorten the set time of these binding agents, and they improve the compressive strength of the products made with them.
