Resumo(s)
Aleppo pine (Pinus halepensis Mill.) is the main forest species of Algeria occupying
more than 35% of the total forest area of the country. However, the
physicomechanical and thermal characteristics of Algerian P. halepensis wood
are not well-known. This research investigates the physical (moisture, density,
swelling, and shrinkage), mechanical (bending strength and modulus of elasticity),
and thermal (mass loss under combustion and pyrolysis as well as thermal
conductivity) properties of P. halepensis wood from the Darguina (Bejaia) forest
in Algeria. The results showed that Algerian P. halepensis wood with a
mean density of 540 kg m-3 has good dimensional stability in swelling and
shrinkage, with 116.43 MPa bending strength and a modulus of elasticity of
17,520 MPa. The wood shows a good thermal resistance under low-temperature
range and has a thermal conductivity of 0.21 W m-1 K-1. The overall results
indicate that Algerian P. halepensis wood may be commercially exploited for
construction and insulation applications, namely in the production of sandwich
composites
