Abstract

In this study, the aim is to inspect the effects of silica aerogel produced from boron waster to compressive strength and thermal performance of bricks. Firstly, silica aerogel was produced by using boron waste obtained from Turkey/Eskişehir/Kırka region. After, silica aerogel produced was mixed into the brick in different proportions, and was baked in 900 °C and 1000 °C to create mixed brick samples. Finally, samples produced was experimented with compressive strength and thermal conductivity coefficient and SEM images were taken. As a result, the increase of aerogel amount caused decrease in compressive strength and thermal conductivity coefficient values in both temperatures. It was observed that amorphous structure increased with the increase of silica aerogel and partial holes and cracks emerged in SEM images. Additionally, when compressive strength was used as basis, it was determined that AB1 sample could be used as holder, while AB2, AB3 and AB4 samples could be used as coating or back filling material in traditional structures. Use of wastes which contain silica such as boron waste in aerogel production is thought to be an appropriate solution for waste disposal.

Özet

Bu çalışmada, bor atıklarından üretilen silika aerojelin tuğlanın basınç dayanımı ve ısıl performansına etkisinin incelenmesi amaçlanmıştır. Çalışma üç aşamada gerçekleştirilmiştir. İlk aşamada Türkiye/Eskişehir/Kırka bölgesinden temin edilen bor atığı kullanılarak silika aerojel üretimi yapılmıştır. İkinci aşamada, üretilen silika aerojel hacimce farklı oranlarda (%0 (REF), %15 (AB1), %25 (AB2), %35 (AB3), %45 (AB4)) tuğla bünyesine ikame edilmiş, 900 oC ve 1000 oC pişirilerek katkılı tuğla numuneleri üretilmiştir. Üçüncü ve son aşamada ise, üretilen numunelere basınç dayanımı ve ısı iletim katsayısı tayini deneyleri uygulanmıştır. Ayrıca numunelerin içyapısının incelenmesi amacıyla SEM görüntüleri alınmıştır. Sonuç olarak; her iki sıcaklıkta da aerojel miktarının artması ile basınç dayanımı ve ısı iletim katsayısı değerinde azalma meydana gelmiştir. SEM görüntülerinde silika aerojel miktarının artmasıyla amorf yapının artığı ve yer yer boşluklar ve çatlaklar oluştuğu görülmüştür. Ayrıca basınç dayanımı baz alındığında; üretilen numunelerden AB1 numunesi taşıyıcı olarak kullanılabileceği, AB2, AB3 ve AB4 numunelerinin ise kaplama veya geleneksel yapılarda duvar dolgu malzemesi olarak kullanılabileceği tespit edilmiştir. Bor atığı gibi silis içeren atıkların aerojel üretiminde kullanılmaları atıkların bertaraf edilmesi için uygun bir çözüm yolu olacağı düşünülmektedir.
