Evaluation of thermal and mechanical properties of the bricks

Abstract EN

A new type of porous brick is proposed.

Feathers Livestock is well mixed initially with wet clay so that when the clay and feathers livestock mixture put in a mold of brick and entered the oven in firing process, voids are created inside it.

The created voids will enhance the total performance of the brick since its reduced density 32 %, thermal conductivity 41 %, and increased compressive stress 18 %, all these properties are measured experimentally and good performance has been obtained.

From this work, it has been obtained that, as porosity increased, the thermal conductivity and density are reduced and a margin reduction in compressive stress is observed but the compressive stress is still larger than that of the common used hollow brick.

These measured data lead to obtain new type of effective brick having good performance with no possibility of mortar to enter inside the holes of the common used hollow brick.

The mortar has a determent effect on thermal properties of the wall.
