Contribution to the investigation of properties of juvenile oak wood (Quercus robur L.)

Investigating the shrinkage of juvenile oakwood, it has been established that it amounts to approximately 0.45% axially, 5.60% radially, 10.61% tangentially, and 15.90% volumetrically. The shrinkage of juvenile wood, compared to adult oakwood, has been higher by 12.5% axially, 15.0% radially, 13.1% tangentially, and 11.8% volumetrically. At 0% moisture content of juvenile oak, the density is ρ₀ = 703 kg/m³, which is 12.5% higher than the compared density of adult oakwood. The nominal density of juvenile oak (ρn = 590 kg/m³) has been 10.3% higher than the same density of compared adult oakwood. These examinations aimed to determine particulars for establishing the extent of over-measure when sawing thin oak logs.
