بعض الخواص الفيزيائية لخشب اشجار الكازوارينا Casuarina Equisetifolia L. النامية في الموصل

الملخص EN

This research was conducted to study the percentages of some wood physical properties of Casuarina equisetifolia L.

grown in Mosul, the study included oven dry density, basic density, volumetric shrinkage, volumetric swelling, Fiber saturation, Green moisture content, Maximum moisture content, Percentage of cell wall, Percentage of the porosity, These characteristics are important to know because they can be highly dependent on the performance and strength of wood used in many applications such as construction applications and others, and the results are as follows: 1-Oven dry density (0.632) g/cm3 .

2-Basic density (0.558) g/cm3 .

3-Volumetric shrinkage (14.051%).

4-Volumetric swelling (14.618%).

5-Fiber saturation point (26.214%).

6-Green moisture content (84.354%).

7-Maximum moisture content (112.723%).

8-Percentage of cell wall (42.1333%).

9-Percontage of the porosity (57.7798%) The relationship was positive between dry density, volumetric shrinkage, volumetric swelling and fiber saturation point, but there is negative relationship between maximum moisture content, percentage of cell wall and percentage of the porosity.

It was found during this study that the Casuarina wood is of medium density with a high shrinkage rate and has a high fiber saturation point as well, which may lead to cracking or twisting when spreading and drying, so it is not suitable for the manufacture of wood panels.
