This paper deals with the measurement of physical properties of various formulations of concrete containing vegetable particles. Such material is made with hemp shives mixed with lime binders. Shives are very porous and as such are also lightweight. Thus, this concrete offers a high porosity related to the microscopic porosity of the shives and the macroscopic porosity due to the arrangement of particles. Moreover, this material offers a ductile behavior and can bear high strain without being damaged. Depending on the binder proportion, the mechanical properties of vegetable concrete cover a wide range: maximum stress of 0.4-1.2 MPa, Young's modulus of 20-90 MPa, and strain at maximum stress of 4-10%. The final aim of this study is to optimize the formulation of vegetable concrete according to its use.
