Abstract


With the development of the wood industry for the needs of construction and furniture, the proliferation of waste thus produced poses serious environmental problems. An interesting avenue for mitigating or absorbing this nuisance would be to develop this substance in the form of a brick with an insulating effect in construction. The object of this study is to characterize the thermal properties of these bricks according to the water content and sawdust. Samples of different sawdust contents (from 0 to 0.33 kgsbkgar-1) with dimensions of 10x10x3 cm3 were produced. An asymmetric hot plane type device was used to measure the volume thermal capacity and the thermal conductivity as a function of the water content from 0 to a maximum value of 0.069 kgdmkgw-1. The profile of the experimental curves of the estimated parameters is in line with that of the theoretical models from the literature.

Author Keywords: Environmental protection, thermal conductivity, volume thermal capacity, clay, sawdust, modeling.
