Abstract

Tükenen kaynakları koruma ve doğa üzerindeki insan etkisini azaltma çabası sonucunda son yıllarda geçirimli betonlar popülerlik kazanmıştır. Özellikle yer altı su kaynaklarını beslemesi, kirleticiler ve ısı adası etkisini azaltması geçirimli betonların avantajları arasında sayılabilir. Sınırlı dayanım özelliklerinden dolayı, bugüne kadar geleneksel betonlar kadar kullanılmamışlardır. Ancak, katkı malzemeleri teknolojisindeki gelişim ve artan çevre bilinciyle birlikte geçirimli betonların adı eskiden olmadığı kadar fazla duyulmaktadır. Bu çalışmada geçirimli betonların fiziksel özelliklerini etkileyen önemli parametrelerden gradasyonun basınç dayanımına etkisi incelenmiştir. Çalışmanın sonucunda kum eklenmesinin basınç dayanımını ciddi oranda arttırabileceği görülmüştür. Ancak, ön deneyler yapılarak kum eklenmesi eşik değerinin belirlenmesi gerekmektedir.

An Experimental Study on Compressive Strength of Pervious Concretes

Abstract

Pervious concretes have gained popularity in recent years, because of human effort to protect depleted resource and reduce effect on nature. Especially resupply ground water resource, reduce effect of pollutants and urban heat island can be regarded as advantages of pervious concretes. Since limited strength properties of pervious concrete, it has not used as much as conventional concrete up to now. However, with development in additive agents technology and rising in environmental consciousness pervious concrete’s name has been heard more frequently than ever before. In this study aggregate gradation, which affects physical properties of pervious concrete, was investigated. At the end of the study, it was seen that addition of sand could increase substantially compressive strength. However, preliminary test should be carried out to determine the threshold of sand addition level.
