Abstract
The invention relates to compressed blocks of wood agglomerate, comprising wood particles and a hydraulic binder, produced by a method in which an initial mixture comprising wood particles and a hydraulic binder is held under pressure for the duration of the hardening of the binder. The invention further relates to a method for production of said blocks and the use thereof in particular, as construction elements for buildings.
Claims9
A block of compressed wood agglomerate, wherein said block comprises particles of wood and a hydraulic binder, and wherein said block is obtained by a process in which an initial mixture comprising particles of wood and a hydraulic binder is kept under pressure throughout the hardening period of the binder, and wherein the initial mixture comprises, for a total of 100% representing the volume of dry matter, from 75% to 95% of particles of wood and from 5% to 25% of hydraulic binder, and a quantity of water between 10% and 30% of the total volume of dry matter.
A process for preparation of a block of wood agglomerate, comprising the steps consisting of forming or pouring in a mould a mixture comprising, for a total of 100% representing the volume of dry matter, from 75% to 95% of particles of wood and from 5% to 25% of hydraulic binder, and a quantity of water between 10% and 30% of the total volume of dry matter, then applying and maintaining the mixture under pressure while the binder hardens.
