The present invention concerns a quick-setting, hydraulic binding agent, containing calcium silicate cement, in particular Portland cement, reactive calcium aluminates, in particular high alumina cement, as well as, if required, known additives and/or admixtures, which is characterized by a content of:a) 0.1 to 2.0% by volume of an organic and/or inorganic accelerator for hydrating the calcium silicates,b) 0.10 to 2.00% by volume of an organic and/or inorganic setting retarder inhibiting the hydration of the calcium silicates, if required, having a liquefying effect,c) 0.01 to 0.05% by volume of an organic and/or inorganic setting accelerator for hydrated calcium aluminate, andd) 0.01 to 0.20% by volume of an inhibitor with respect to formation of the hydrated calcium aluminum sulfates. |
