A new type of porous brick is proposed where sawdust is initially mixed with wet clay
to induce voids inside the brick during the firing process. The proposed types are found to have
low density, low thermal conductivity, and high compressive stress which may be the best
choice for a brick and the proposed brick is even better than the common type of hollow brick
used in Middle East. From this work, it has been obtained experimentally that, as porosity increased,
the thermal conductivity and density are reduced and a margin reduction in compressive
stress is observed. The compressive stress of the new proposed bricks is still larger than that
of the hollow bricks widely used in developing countries. The new brick has no holes assume
