Öz

Hafif agregalarla yapılan hafif betonlar genel olarak; geleneksel betona göre daha düşük birim hacim ağırlığa, daha iyi ısı yalıtım ve yangın direnci özelliklerine sahiptirler. Önemli hafif agregalar arasında yer alan genleştirilmiş kil agregası (GKA) en iyi basınç değeri veren hafif agregalar arasında yer almaktadır. Bu çalışmada agrega olarak 0-500 µm, 0-3 mm, 3-8 mm, 8-16 mm ebatlarında GKA ve 4 farklı süperakışkanlaştırıcı katkı malzemesi (SA) kullanılarak, su/çimento (S/C) oranı 0.40, 0.45, 0.50 oranlarında hazırlanan numuneler üzerinde fiziksel ve mekanik deneyler yapılmıştır. Yapılan yayılma, basınç dayanımı, birim ağırlık, su emme ve kılcal su emme deneylerinin sonuçları değerlendirildiğinde, çalışmada kullanılan süperakışkanlaştırıcı katkıların bu hafif agregalı beton için uygun tipte olduğu anlaşılmıştır.
