Abstract:
1. A method for producing a wood wool construction element, comprising the steps of: a) providing a mould having a bottom and at least two side walls, preferably two oppositely placed side walls; b) providing a mixture of wood wool and a hydraulic binder; c) dispersing at least a part of said mixture in the mould so as to provide a layer of the mixture, said layer having a height that is less than the height of the side walls; d) at least partially hardening said mixture dispersed during step c) in the mould; e) repeating steps c) and d) with the provision that a final layer of mixture is added in step c) when the total height of the mixture in the mould exceeds the height of the side walls of the mould, with the proviso that after partially hardening said mixture dispersed during at least one step c) such that a subsequently dispersed layer of said mixture provides a settlement of less than 50% and before performing a subsequent step of dispersing another part of said mixture, a pillar is placed in the mould, said pillar extending, between two opposed side walls or between a side wall and a beam positioned against an opposite side wall; and f) positioning a cover on top of the mould so as to compress the mixture in said mould with a bottom side of said cover to a height substantially equal to the height of the side walls of the mould, and hardening the mixture.
