Abstract

Historically, finding decent and affordable housing has been a major concern for people. The advantages of bamboo such as a renewable, ecological material, its fast growing and its low cost, allow it to be considered as a substitute for common nonrenewable materials. Using of raffia bamboo in construction as support, scaffold and carrying girder it's not subject to any norm recommend. It's very important to know his mechanical properties before use it in this field. The objective of this paper is to investigate the mechanical properties in tension, shear and bending. The method used is experimental. All test protocols were conducted in accordance with French standard EN NF 408. The results obtained show that the stiffness in the direction of the fibers of raffia shell (16905 MPa) is close to that of heavy woods. The marrow exhibits behavior similar to ductile materials. The experimental results have shown that it has a high capacity for deformation before breaking and a very weak elastic phase. Simple shear tests conducted on the shell in the direction of bamboo fibers have shown that the shear stress changes as the section becomes large. The convincing explanation attributed to this observation is the sensitivity of the dimension effect on the mechanical properties. All the data from the test campaigns allows us to catalog the raffia species among the promising renewable materials in construction.
