Moisture absorption and dimensional stability of poplar wood impregnated with sucrose and sodium chloride

This paper deals with the effect of vacuum-pressure impregnation of Poplar wood (Populus alba) by aqueous solutions of sucrose and sodium chloride on its physical properties. Groups of samples with different concentrations of substances in the aqueous solution were compared within each other and als...
