Energy consumption in the building sector is
constantly increasing and represents more than 44% in the residential and
tertiary sectors in many countries[1]. Thus, the building represents a real possibility of energy saving and
is the subject of several studies particularly in actual context of
experimentation with materials based on plant fibers (hemp, flax,
millet wastage, etc.). These biobased materials such as typha have shown real
interest in the buildings construction due to their light and porous nature.
It’s in this context that we were interested in typha australis mixed with
classic aggregates (cement, sand, gravel 3/8) to make typha’s concrete. On this
concrete, we carried out experimental measurements in order to better
understand its contributions in the building. The interesting results obtained
show that typha australis, which is an invasive and harmful grass, can be
valued and integrated among local building materials in the form of typha’s
concrete in order to improve the energy efficiency of buildings.
