METHOD FOR PRODUCING A BUILDING ELEMENT AND BUILDING ELEMENT FORMED

摘要

A method is described for producing a building element in which a hardenable binder-material is mixed with a coarse particles comprising material after which the mixture is used for forming unhardened building elements. The building elements are subsequently hardened at a temperature up to 100 DEG C. and at atmospheric pressure in a water-vapor containing atmosphere. The hardenable binder material is constituted by a separately prepared mixture of fly ash; Ca(OH)2 or a substance which may be converted into Ca(OH)2, and water. Optionally the hardenable mixture may be partially granulated before use.
