Beschreibung
Zusammenfassung:	The present invention relates to the use of an amino alcohol A and/or of a salt of said amino alcohol A as a hardening accelerator for mineral binders, in particular cementitious binders. The amino alcohol A has a structure according to formula (I) where a) R1 and R2, independently of one another, each represent an alkanol group comprising 3 - 4 carbon atoms, b) R3 is an organic group comprising 1 - 8 carbon atoms, and c) R3 is different from R1 and/or R2.
