Arundo donax: A widespread plant with great potential as sustainable structural material
Highlights A complete mechanical characterization of Arundo donax was carried out. The axial Young’s moduli were 12.0 GPA and 14.8 GPa under compression and tension. Methods are proposed to characterize the shear, axial and transverse tensile behavior. The anisotropy and mechanical properties of AD are similar to those of bamboo used in construction. DIC was used to analyze the role of the anisotropy and natural nodes under various loading conditions.
Abstract There is a growing recognition and awareness that nature can provide viable solutions for more sustainable building materials. Arundo donax (AD) is a tall cane of about 20–30 cm in diameter that grows widely and rapidly in many regions of Europe. AD, like bamboo in the subtropical areas, may be rediscovered as a source of inexpensive sustainable material for various construction purposes. To promote the use of AD following the engineering practice, this paper was aimed at showing the potentiality of this material through an extensive mechanical characterization. The tests were performed on portions of culms using ad hoc setups following recommendations or modifications of bamboo standards. Digital image correlation was used to follow the map of strains needed to understand the role of the natural nodes under different loading conditions. The axial Young’s moduli were 12.0 GPa and 14.8 GPa under compression and tension, respectively, and the corresponding maximum failure stresses were 57 MPa and 127 MPa for the internodal material. Shear and transverse bending tests yielded results consistent with the anisotropy of the material. The results show the good mechanical properties of Arundo donax that are similar to those of various species of bamboo used in constructions.
