Abstract

In a context of sustainable development and reduction of energy consumption in the building sector, plant-based concretes are increasingly developed. These materials offer excellent thermal properties, with low mechanical properties, but sufficient for use as a filling material. Moreover, Typha is an invasive plant with harmful consequences on our environment. This work investigates the valorization of recycled lime in Typha-cement thermal insulation materials. The mechanical and thermal properties of these composites are studied according to lime percentage used in substitution of cement. The results show that the compressive strength of the concrete ranges from 1.34 to 2.30 MPa. Thermal results range from 0.078 to 0.192 W.m−1K−1for thermal conductivity and 385.68 to 505.18 J.m−2. K−1.({\mathrm{s}}^{-\frac{1}{2}})for thermal effusivity.
