METHOD FOR PRODUCING A BONDED ARTICLE COMPRISING A PRESS-MOULDED, CARBONATED GRANULAR MATERIAL

摘要

The present invention relates to a method for producing a bonded article by press-moulding and carbonating a granular, carbonatable material. The granular material is applied in a mould, is press-moulded therein under a compaction pressure of at least 25 MPa, and is carbonated during said press-moulding step by means of a gas which contains at least 1 vol.% of carbon dioxide. By carbonating the material when press- moulding it, high compressive strengths can be achieved in a short period of time.
