GEOPOLYMER-BINDER SYSTEM FOR FIRE CONCRETES, DRY FIRE CONCRETE MIX CONTAINING THE BINDER SYSTEM AND ALSO THE USE OF THE MIX

摘要

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.

1. Alkaline-activated binder system for fire concretes, composed of at least a mineral binder and a mineral activator, which form a curing geopolymer in a mixture with water,
wherein a combination of at least two magnesium components (Mg components) that react with water in alkaline manner and, in this connection, reactively form a geopolymer with the binder in different manner, in terms of time, is contained as an activator, wherein the magnesium components demonstrate a different reactivity with regard to humidity in the air and/or with regard to the binder.
