The wood is ground, then mineralized with the aid of the cement (or concrete); this mix, via a block-making machine, is turned into solid blocks. In this way the porous structure, which is very important for the transpiration of the masonry, is not destroyed. The formwork blocks are laid dry, thereby eliminating the various drawbacks caused by the use of mortar, subsequ...
