method for achieving fire released concrete elements, elements and structures that implement these elements.

摘要

The formwork elements (4, 5, 6, 7), for example for a column (1), are produced totally or partially from a fireproof material preferably comprising a finely divided cellulose substance as well as a mineral substance and a synthetic resin. The concrete is then poured into these formwork elements which have, on their internal face, bonding members (8) and which are then kept as permanent protective formwork units. This method applies to all types of constructions, particularly of the type comprising a structure made up of columns, beams, panels, etc. IMAGE
