The use of new materials for thermal comfort is becoming more and more a priority in the construction of comfortable and economical homes. It is in this context that, in our previous work, we developed bricks based on Iroko wood flour compressed and stabilized with recycled High Density Polyethylene (HDPE) resin. There are six samples with respective contents of 10, 20, 30, 40, 50 and 60%. This article aims to present an experimental study followed by a simulation using the Cast3M calculation code of their thermal behavior. To do this, we first determined their thermophysical properties which are thermal conductivity, specific heat and thermal diffusivity. Then, after a study of the depth of heat diffusion in the different samples, we moved on to the simulation phase. It focused on the analysis of the effects of the HDPE rate, the thickness of the bricks and the air temperature. As results, the values of thermal conductivity, specific heat and thermal diffusivity, for all the composites, vary respectively from 0.310 to 0.365 W.m-1.K-1, from 2.691 to 2.460 kJ.kg-1.K-1 and from 1.662 to 1.981.10-7m2.s-1. Thermal conductivity, thermal diffusivity and diffusion depth increase with increasing HDPE content; while the specific heat decreases. It also appears that for the temperature of 45°C imposed for a thickness greater than 2.7 cm, it is necessary to wait a time greater than at least 22 hours to reach a stationary state on the opposite side. From all of the above, it could be affirmed that the elaborate bricks have intrinsic capacities to be used in the construction of thermally comfortable habitats in local temperature conditions such as those of the Ivory Coast.

Abstract
The use of new materials for thermal comfort is becoming more and more a priority in the construction of comfortable and economical homes. It is in this context that, in our previous work, we developed bricks based on Iroko wood flour compressed and stabilized with recycled High Density Polyethylene (HDPE) resin. There are six samples with respective contents of 10, 20, 30, 40, 50 and 60%. This article aims to present an experimental study followed by a simulation using the Cast3M calculation code of their thermal behavior. To do this, we first determined their thermophysical properties which are thermal conductivity, specific heat and thermal diffusivity. Then, after a study of the depth of heat diffusion in the different samples, we moved on to the simulation phase. It focused on the analysis of the effects of the HDPE rate, the thickness of the bricks and the air temperature. As results, the values of thermal conductivity, specific heat and thermal diffusivity, for all the composites, vary respectively from 0.310 to 0.365 W.m-1.K-1, from 2.691 to 2.460 kJ.kg-1.K-1 and from 1.662 to 1.981.10-7m2.s-1. Thermal conductivity, thermal diffusivity and diffusion depth increase with increasing HDPE content; while the specific heat decreases. It also appears that for the temperature of 45°C imposed for a thickness greater than 2.7 cm, it is necessary to wait a time greater than at least 22 hours to reach a stationary state on the opposite side. From all of the above, it could be affirmed that the elaborate bricks have intrinsic capacities to be used in the construction of thermally comfortable habitats in local temperature conditions such as those of the Ivory Coast.
