ABSTRACT: This article deals with the characterization of local materials
used in insulation building heat. These materials are bricks of earth compressed
and stabilized with rice husks. Thermal conductivity, the specific heat and the
thermal diffusivity of materials based on clay incorporating rate of 0, 2%, 4%, 6%, 8% and 10%
are determined. The results showed that the clay blocks + rice balls had better
thermal insulators than simple clay blocks. However, these composite materials used
for the envelope of the building must have sufficient mechanical resistance when
used in construction. The measurement of mechanical properties such as compressive
strength showed an improvement of 6% and beyond, a drop in resistance when increasing
rice husks in clay is observed. These results allow to specify the optimal conditions
of use of these materials for the building envelope.
