Use of Granular Aerogel in Lightweight Blend Brick: On Thermal Properties and Compressive Strenght

Abstract

Blended bricks can be defined as the ancestor of the fabricated bricks used today, although they are not preferred much today. The development of technology has led to changes in the properties and form of blended bricks. The use of blended bricks, which we frequently encounter in architectural applications, continues, albeit less than in the past. Today, it continues its activities in many areas, especially restoration projects. In this study, it was aimed to produce blended bricks with improved thermal insulation, low unit weight and compressive strength accordance to TS standards by substituting granular aerogel, which is a nanomaterial, into the blended brick body. In the study, brick samples containing 0%, 2.5%, 5%, 7.5% and 10% granulated aerogel were produced. Acidic pumice used for lightweight brick production was kept constant at 50%. Lightweight blended brick samples were fired at 900 oC and 1000 oC. As a result of the study, blended brick samples with improved thermal insulation properties, low unit weight and compressive strength in accordance to the required standards were produced.
