Anew type of porous clay bricks is proposed , this research studies the effect of adding industrial wastes admixtures with different percentages on the thermal and acoustics insulation properties of clay bricks . Different types of admixtures were used in this work ,including plastic cuttings ,wood saw dust ,palm fiber with ( 5% ,10% ,15% ,20 ) percent of weight of each one . Acoustics insulation , thermal conductivity ,specific heat capacity ,porosity and variation of density have been examined for each samples at all percent of admixtures and comparing with the reference clay bricks samples . Form the obtained test result show the admixtures effect on the properties of clay bricks , the best material which can used from this paper is palm fiber to get the best properties of acoustic insulation , thermal conductivity and density for 20% admixtures percentage comparing with the standard bricks .
