Gazbetonun Malzemesinin Isıl İletkenliğinin Farklı Gözeneklilik Oranlarında İncelenmesi

Binalarda
ısınma maliyetlerinin azaltılması için uygun yapı elamanları kullanarak
yalıtım  yapılmalıdır. Bu açıdan gazbeton
yapı sektöründe çok önemli bir yere sahiptir. Gazbeton gözenekli yapıya sahip
hafif beton sınıfında yer alan bir yapı malzemesidir. Bu çalışmada gazbeton
malzemesinin gözeneklilik oranına bağlı olarak ısıl iletkenlik değeri analitik,
sayısal ve deneysel olarak belirlenmiştir. Analitik inceleme yapılırken gözenek
oranları dikkate alınarak literatürde yer alan ısıl iletkenlik hesap modelleri
kullanılmıştır. Sayısal incelemede elektron mikroskopta elde edilen görüntüler
(SEM) kullanılarak gazbetona ait geometrik model oluşturulup tek boyutlu çözümler
elde edilmiştir. Gazbetonda kireç, çimento ve alüminyum tozunun reaksiyona
girmesi nedeniyle kabarcıklar oluşmaktadır. Sayısal çözümler yapılırken hava
kabarcıklarının ısıl iletkenliğinin sıcaklığa bağlı olarak değiştiği,
kuvarsitin sıcaklıkla değişmediği değerler kullanılmıştır.  Sayısal çözümlerde sonlu eleman esaslı
(ANSYS) programı kullanılmıştır. Çözümlerde sabit yüzey sıcaklığı sınır
şartları altında ısı akısı hesaplanmıştır. Deneysel çalışmalar Laser Flash
teknoloji kullanan cihazla farklı gözeneklilik oranlarında yapılmıştır.
Çalışmanın sonunda analitik, sayısal ve deneysel sonuçlar karşılaştırmalı
olarak verilmiştir.
