Physical Mechanical Properties of Laminated Beam of Eucalyptus Grandis: A Sustainable Solution for the Construction Industry

Introduction

The increasing demand for wood raw materials has led to a significant concern about the sustainability of ecosystems and forest conditions. The limited supply of wood has raised questions about the long-term viability of the construction industry. In response to this challenge, researchers have been exploring alternative sustainable construction materials. One such alternative is Eucalyptus Grandis, a species of eucalyptus that is abundant and has the potential to help overcome environmental problems.

Background

Eucalyptus Grandis is a fast-growing tree species that is widely available in many parts of the world. Its wood is known for its durability and resistance to decay, making it an attractive option for construction materials. However, the use of Eucalyptus Grandis wood as a raw material for laminated beams has not been extensively studied. This study aims to investigate the physical and mechanical properties of laminated beams made from Eucalyptus Grandis wood.

Methodology

This study used Eucalyptus Grandis wood to create laminated beams with 3 layers and 5 layers. The beams were glued using an isocyanate and PVAC adhesive with a ratio of 100:15. The physical properties of the laminated beams were evaluated based on ASTM D 143-94 standards, while the mechanical properties were assessed based on ASTM D 143-94 standards and Jas for Glued Laminated Timber.

Results

The results of this study showed that:

  1. Density: Lamination beams with 3 layers have a density of 0.66 kg/cm³, while laminated beams with 5 layers have a density of 0.62 kg/cm³. This indicates that the density of the laminated beams decreases with an increase in the number of layers.
  2. Water content: Laminated beams with 3 layers have a water content of 14.02%, while laminated beams with 5 layers have a water content of 14.46%. This suggests that the water content of the laminated beams increases with an increase in the number of layers.
  3. Modulus of elasticity (horizontal): Laminated beams with 3 layers have a modulus of elasticity of 131.90 kgf/cm², while laminated beams with 5 layers have an elasticity modulus of 124.97 kgf/cm². This indicates that the modulus of elasticity of the laminated beams decreases with an increase in the number of layers.
  4. Modulus of elasticity (vertical): Lamination beams with 3 layers have a modulus of elasticity of 192.37 kgf/cm², while laminated beams with 5 layers have a modulus of elasticity of 233.31 kgf/cm². This suggests that the modulus of elasticity of the laminated beams increases with an increase in the number of layers.
  5. Modulus Rupture (horizontal): Lamination beams with 3 layers have a rupture modulus of 377 kgf/cm², while laminated beams with 5 layers have a modulus rupture of 329 kgf/cm². This indicates that the modulus rupture of the laminated beams decreases with an increase in the number of layers.
  6. Modulus rupture (vertical): Laminated beams with 3 layers have a rupture modulus of 708 kgf/cm², while laminated beams with 5 layers have a rupture modulus of 743 kgf/cm². This suggests that the modulus rupture of the laminated beams increases with an increase in the number of layers.
  7. Hot water immersion delamination test: Laminated beams with 3 layers show a delamination of 38.22%, while laminated beams with 5 layers indicate delamination of 41.10%. This indicates that the delamination of the laminated beams increases with an increase in the number of layers.

Discussion

The results of this study indicate that the use of Eucalyptus Grandis wood as a raw material for laminated beams has good potential as an alternative construction material. The physical and mechanical properties of the laminated beam of the Grandis Eucalyptus are strong enough and meet the established standards. However, further research needs to be done to optimize the laminated process and the type of adhesive used, so that laminated beams can be obtained with better quality and longer durability.

Conclusion

This study has demonstrated the potential of Eucalyptus Grandis wood as a sustainable construction material. The physical and mechanical properties of the laminated beam of the Grandis Eucalyptus are strong enough and meet the established standards. However, further research is needed to optimize the laminated process and the type of adhesive used, so that laminated beams can be obtained with better quality and longer durability. This research also opens opportunities to utilize forest resources in a sustainable manner and reduce pressure on natural forests.

Limitations

This study has several limitations that need to be addressed in future research:
