Evaluated the influence of the concentration of sodium chloride in the dimensional stability of Eucalyptus urophylla x Eucalyptus grandis. It was used 90 samples, which were saturated in beakers containing distilled water (control) and sodium chloride solution concentrations of 2.5% and 10%. Once saturated, the samples were dried until constant mass. The dimensions of the samples were determined for calculate the swelling and radial and tangential contractions. Woods of Eucalyptus urophylla x Eucalyptus grandis impregnated with sodium chloride solution at concentrations of 2.5 and 10% obtained tangential swelling values similar to those of the control. For radial swelling, wood impregnated with sodium chloride solution at a concentration of 2.5% reached lower values. The concentration of sodium chloride solution influenced the tangential and radial contraction of Eucalyptus urophylla x Eucalyptus grandis woods, as lower values were found for woods impregnated with sodium chloride solution at concentrations of 10 and 2.5%.
