This study presents the elaboration and characterization of a composite material based on Typha australis and clay for the use of an innovative building material in construction. For this purpose, various percentages ranging from 0 to 55% with a pitch of 15 were used. The aim is to find a better compromise between the thermal and mechanical properties of this composite material. According to this, the influence of the length of the 1 cm and 3 cm fibers was studied. As Typha australis is very porous, the hydric properties of the material studied in this work show that its porosity increases the rate of water absorp tion following a logarithmic law and the mass loss of the composite material evolves exponentially as a function of time. The mass increases when the percentage of fibers is low. The thermophysical property of Typha australis is 0.06 W/m K. That property allows us to state that Typha australis can be used for thermal insulation.
