Selected properties of Blue spruce wood from non-forest land
The aim of this work was to carry out a tree-ring analysis, to determine density, shrinkage and compressive strength parallel to the grain of Blue spruce (Picea pungens Engelm.) wood. Results of this work were specific due to the non-forest origin of the sample material that was from two solitaire t...
