Improvement of The Mechanical and Thermal Properties of Clay Bricks by Using Local Materials in Iraq

Abstract

This research studies the effect of adding industrial wastes materials withdifferent percentages on the thermal and mechanical properties of claybricks . Different types of admixtures were used in this work, includingrubber cuttings, wood saw dust and barley reeds ash with ( 5%,10% 15%,20% ) by weight of each one respectively. Thermal conductivity, specific heatcapacity, compressive strength, flexural tensile strength, porosity and variationof density have been examined for each samples at all percent of additionand comparing with the reference clay bricks samples . Test results show thatthe admixtures effect on the properties of clay bricks, when used barley reedsash which the best additives because take good properties, the density of claybricks is reduced 33%,thermal conductivity reduced 46% and the compressivestrength increased 20% comparing with the standard bricks. The experimentalwork carried in the industrial factory of clay bricks in the Nahrawon city inBaghdad.
