Evaluation of acoustics insulation and thermal conductivity through walls in a building

Abstract EN

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.
