Abstract:
1. A method for producing a chemically bound ceramic material by reacting a binding phase of one or more powdered binding agents and a hydration liquid reacting with these binding agents, a quantity of powder containing said binding phase being suspended in said hydration liquid so that all powder grains are brought into close contact with the hydration liquid, draining the slurry thus obtained so that the majority of the surplus reacting hydration liquid is removed, compacting the slurry during final draining, before hardening the material by reaction between said binding phase and the remaining hydration liquid, wherein one or more expansion-compensating additives, are mixed into said powdered binding phase, prior to or in connection with its suspension in the liquid and wherein said binding phase comprises calcium aluminate cement, wherein a compression strength of said chemically bound ceramic material is in the range of 170-200 MPa.
