Experiment code 21.5.3.11
Experiment Title Assessment of physical and mechanical properties of different bamboo species
Research Type Departmental Research
Experiment Background Bamboo is one of the oldest building materials used by mankind in tropical and subtropical regions. It meets the need of common people, helps in uplifting the poverty of local people due to its multipurpose uses. It is a suitable species for plantations and now it is also explored for agroforestry and farm forestry and generally utilized for domestic household products, pulp and paper, furniture and structural purposes in construction sectors. Dendrocalamus strictus and Bambusa bambos are the common bamboo species which have been widely studied in India for various end applications. Limited studies have been carried out on many other bamboo species for strength quality in India and especially in Gujarat. Therefore, an investigation on the physical and mechanical properties of different bamboo species planted in Bambusetum of College of Forestry is required to know their mechanical strength for various end applications. Hypothesis It was assumed that there is no variation in the physical properties and mechanical strength of different bamboo species

03 REPLICATIONS

OBSERVATIONS TO BE RECORDED

  • Culm height (m)
  • Culm diameter (cm)
  • Moisture content (%)
  • Basic density (g/cm3)
  • Shrinkage along diameter (%)
  • Shrinkage along wall thickness (%)
  • Shrinkage along length (%)
  • Volumetric Shrinkage (%)
  • Static Bending Strength (N/mm2)

    a) The ultimate strength (MOR)

    b) The modulus of elasticity (MOE)

  • Compressive Strength Parallel to Grain (N/mm2)
  • Tensile Strength Parallel to Grain (N/mm2)

METHODOLOGY

  • Samples of bamboo species will be collected from the middle portion of the entire bamboo culm of each species. Minimum 3 culms will be selected from 3 different clumps of each bamboo species for the assessment of physical and mechanical properties.
  • Physical properties of bamboo: Moisture content, basic density and shrinkage will be determined from the cross-section of bamboo internodes.

Mechanical properties The selected samples, free from defects like cracks and crookedness will be air-dried and conditioned and tested in a computerized Universal Testing Machine (UTM) of 5 tons loading capacity capable of measuring load to the nearest 100N and deflection to the nearest 1mm for determination of static bending strength, compressive strength parallel to grain and tensile strength parallel to grain
