Abstract
Our work expressed that compressed and stabilized clay with arabic gum is a suitable building material in regards to the mechanical properties. This paper presents an experimental study of the determination of thermal conductivity in a steady state cylindrical geometry configuration approach.
The results obtained give a thermal conductivity in the order of 1 W.m-1. K-1, quite similar to other building materials. On the other hand, because of its inertia, the material dampens the temperature variations between the inside and the outside.
Keywords: Compressed clay block, clay, gum Arabic, thermal conductivity, thermal inertia, damping the température.
