    Abstract: An alkaline-activated binder system for fire concretes includes at least one mineral binder and a mineral activator which, in a mixture with water, form a curing geopolymer, where a combination of at least two magnesium components (Mg components) which give an alkaline reaction with water and react with the binder at different times to form a geopolymer is present as activator, where the magnesium components have a different reactivity in respect of atmospheric moisture and/or in respect of the binder. A dry fire concrete mix contains the binder system and the mix may be used in, for example, facilities in the steel industry.
