The effect of using scrap tire powder in the perforated brick holes on thermal insulation

Abstract

In this study, old scrap tire powder was used with building materials commonly used in Iraq, where it was used in some brick holes in the form of powder 0-1 mm ( crumb rubber without fabric and metal), and this case, it was called scrap tire powder in bricks [STP-I]. It was compared with the traditional wall that does not contain scrap tires, called [No STs]. A test room has been build prepared for this purpose and a heating source for 8 hours applied on each wall. The comparison was by measuring the temperatures on the inner and the outer surfaces as well as the center of the wall, and comparing the thermal resistance and the heat transferred. The results noted that the addition of this material might be reducing the internal surface temperature by 2.56℃, which is a good incentive for this material's role as a thermal insulator.
