Harman tuğla, günümüzde pek tercih edilmese de şimdilerde kullanılan fabrikasyon tuğlaların atası olarak tanımlanabilmektedir. Teknolojinin gelişmesi harman tuğlanın özelliklerini ve formunun değişmesine yol açmıştır. Mimari uygulamalarda sıklıkla karşımıza çıkan harman tuğla kullanımı eskiye nazaran az da olsa devam etmektedir. Günümüzde, restorasyon projeleri başta olmak üzere birçok alanda etkinliğini sürdürmektedir. Bu çalışmada, harman tuğla bünyesine nanomalzeme olan granül aerojel ikame edilerek ısı yalıtımı iyileştirilmiş, birim ağırlığı düşük ve TS standartlarına uygun basınç dayanımına sahip harman tuğla üretimi amaçlanmıştır. Çalışmada, hacimsel olarak, %0, %2,5, %5, %7,5 ve %10 oranında granül aerojel killi toprak ile yer değiştirilmiş ve katkılı tuğla numuneleri üretilmiştir. Hafif tuğla üretimi için kullanılan asidik pomza %50 oranında sabit tutulmuştur. Hafif harman tuğla numuneleri 900 oC ve 1000 oC’de pişirilmiştir. Çalışma sonucunda, ısı yalıtım özellikleri iyileştirilmiş ve istenilen standartlara uygun basınç dayanımına sahip harman tuğla numuneleri üretilmiştir.

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

Öz

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, granulated aerogel is replaced with clay soil with 0%, 2.5%, 5%, 7.5% and 10% by volume and additived brick samples are produced. Acidic pumice used for lightweight brick production was kept constant at 50%. Lightweight blended brick samples are fired at 900 oC and 1000 oC. As a result of the study, blended brick samples with improved thermal insulation properties and compressive strength in accordance to the required standards were produced.
