COMPARING BAMBOO TO WOOD
Bamboo and wood are 2 popular materials in architecture today. Althought they bring the unique beauty, bamboo and wood have different mechanical properties for each work. Let’s compare bamboo to wood to find the most suitable material for your work!
| BAMBOO | WOOD | |
| Harvest time | 3-5 years | 20-50 years |
| Classify | Grass | Wood |
| Soil | Garden, forest, riverside, flank | Forest |
| Initial cost | Low | High |
| Absorb CO2 | =4X | =X |
| Release O2 | = 1,35 Y | = Y |
| Protect soil | Planting bamboo prevents soil erosion and flash flood | Each region will grow different types of wood (Indonesia grows Mahogany, Peltophorum tonkinensis Pierre, Acacia, Brazil grows rubber and cacao, Vietnam grows Gmelina arborea Roxb). |
| Weight | Light | Light wood (Sycamore, Zenia insignis,…), heavy wood (Iron wood, Lauan meranti,…) |
| Structure | Fibrous | Grain |
| Ductility | Being easy to bend and good load-bearing after bending. | Can be bent, wood’s ductility is less than vertical strength and greater than vertical compression strength. Structures can be bent such as beam, truss,.. No elasticity, so it cannot load-bearing after bending. |
| Renewable | After harvesting, bamboo will be renewable itself without planting new tree. | Planting new tree after harvesting. |
| Tensile strength | Higher than steel | Lower than steel |
| Compressive strength | Higher than concrete | Lower than concrete |
| Tensile resistance | 6 times greater than steel | Lower than bamboo |
| Mechanical property | =3Z | =Z |
| Life expectancy of work | Up to 50 years | 50-70 years |
| Hardness | Be 27% more as hard as oak | Medium |
| Cost | Cheaper than wood | Expensive |
