Improvement of the mechanical and thermal properties of clay bricks by using local materials in Iraq

الملخص EN

This research studies the effect of adding industrial wastes materials with different percentages on the thermal and mechanical properties of clay bricks.

Different types of admixtures were used in this work, including rubber cuttings, wood saw dust and barley reeds ash with (5 %, 10 %, 15 %, 20 %) by weight of each one respectively.

Thermal conductivity, specific heat capacity, compressive strength, flexural tensile strength, porosity and variation of density have been examined for each samples at all percent of addition and comparing with the reference clay bricks samples.

Test results show that the admixtures effect on the properties of clay bricks, when used barley reeds ash which the best additives because take good properties, the density of clay bricks is reduced 33 %, thermal conductivity reduced 46 % and the compressive strength increased 20 % comparing with the standard bricks.

The experimental work carried in the industrial factory of clay bricks in the Nahrawon city in Baghdad.
