Abstract: An experimental study was carried out in order to determine the properties of local materials used for building thermal insulation.
Cement stabilised compressed clay bricks were tested.
The thermal conductivity and specific heat of laterite based materials incorporating pouzzolane or sawdust was determined.
The experimental results showed that pouzzolane + laterite bricks or sawdust + laterite bricks give better thermal insulation than simple laterite bricks.
However, these composite materials used for building shielding must present sufficient mechanical strength to be suitable for constructions.
The measurement of mechanical properties such as compressive strength and tensile strength showed little difference between the strength of the three studied materials.
The tensile strengths of the laterite and the laterite + pouzzolane bricks were similar.
They were about two times that of the laterite + sawdust bricks.
The obtained thermal and mechanical results permit to specify the optimal use conditions of the tested materials.
