ABSTRACT. This study deals with the chemical treatment of the Acacia Auriculiformis species with a 99.5% glycerol solution with the aim of demonstrating the possibility of producing better ultimate compressive strength parallel to the grain upon drying. The vacuum pressure method was used to impregnate the glycerol solution into the cell wall of the wood. The results indicate a significant improvement (about 30% higher) of the properties investigated; specifically the compressive strength of wood perpendicular to the grain, however, the non-impregnated sample still has superiority when it comes to toughness.
