Bu çalışmada, F ve C sınıfı uçucu küllerin betonun mekanik özelliklerine etkisinin karşılaştırılması amaçlanmıştır. Bu amaç doğrultusunda, beton üretimine katkı olarak %15, %20 ve %25 oranında F ve C sınıfı uçucu kül ayrı ayrı kullanılarak beton üretimi yapılmıştır. Üretilen numunelere mekanik deneyler (basınç dayanımı, eğilme dayanımı) uygulanmıştır. Deneyler sonucunda elde edilen veriler grafiklere aktarılıp yorumlanmıştır. Sonuç olarak, C sınıfı uçucu külün F sınıfı uçucu küle kıyasla daha yüksek basınç dayanımı ve daha iyi eğilme dayanımı sağladığı görülmüştür. Ayrıca uçucu kül gibi atıkların beton endüstrisinde kullanılmasıyla atıkların bertaraf edilmesine katkıda bulunulacağı sonucuna varılmıştır.

Comparison of the Effect of F and C Class Fly Ash on the Mechanical Properties of Concrete

Öz

In this study, it was aimed to compare the effect of F and C class fly ash on the mechanical properties of concrete. For this purpose, 15%, 20% and 25% F and C class fly ash were produced separately as a contribution to the production of concrete. Mechanical experiments (compressive strength, bending strength) were applied to the produced samples. The data obtained as a result of the experiments are transferred to the graphics and interpreted. The data obtained as a result of the experiments are transferred to the graphics and interpreted. In addition, it has been concluded that wastes such as fly ash will contribute to the disposal of waste by using it in the concrete industry.
