The results of an experimental study on the thermal and mechanical properties of concretes using porous aggregates instead of conventional aggregates are presented in this study. Oriented at this purpose, eleven concrete samples containing organic sediment stones, volcanic stones and artificial porous aggregates were prepared as porous aggregates. The concrete samples were subjected to certain tests at the end of 28 days of drying period and their thermal and mechanical properties were determined accordingly. With this study, the following values were obtained: i) The lowest heat transfer coefficient for concrete with expanded polystyrene aggregates from the group of artificial porous aggregates: 0.175 W/mK, ii) The highest compressive strength value is basalt-type stone (Karaca dag) from the group of volcanic stones: 117 MPa.

Gözenekli Agregalı Betonların Isıl ve Mekanik Özellikleri

Öz

Bu çalışmada, geleneksel agrega yerine gözenekli agrega kullanılan betonların ısıl ve mekanik özellikleri üzerine yapılan deneysel bir çalışmanın sonuçlan sunulmuştur. Bu amaçla gözenekli agrega olarak organik sediment taşlar, volkanik taşlar ve yapay gözenekli agregalar ihtiva eden on bir adet beton numuneler hazırlanmıştır. Beton numuneler, 28 günlük kuruma sureci sonunda bazı testlere tabi tutularak ısıl ve mekanik özellikleri belirlenmiştir. Bu çalışma ile i) en düşük ısı iletim katsayısı, yapay gözenekli agregalar gurubundan genleşmiş polistiren agregalı beton 0.175 W/mK olarak, ii) en yüksek basma gerilmesi değeri volkanik taşlar gurubundan basalt-type stone (Karaca dag) 117 MPa olarak belirlenmiştir
