Abstract

In this study, it was aimed to investigate the effect of ground blast furnace slag replacement on the physical and mechanical properties of roller compacted concretes. In the experimental study, roller compacted concretes were produced by using ground blast furnace slag as 10%, 20% and 30% of the weight of portland cement. The percentage of compactibility, unit weight, ultrasonic pulse velocity, dynamic modulus of elasticity, water absorption, and concrete compressive strength at the ages of 3 and 28 days were determined. With the use of blast furnace slag in roller compacted concretes, workability of concrete was positively affected and the percentages of compactibility increased. The replacement of blast furnace slag caused a decrease in 3-d concrete compressive strength, while it increased the 28-d concrete compressive strength.

Özet

Bu çalışmada, öğütülmüş yüksek fırın cürufu ikamesinin silindirle sıkıştırılmış betonun fiziksel ve mekanik özelliklerine etkisinin araştırılması amaçlanmıştır. Deneysel çalışmada, Portland çimentosunun yerine ağırlıkça %10, %20 ve %30 oranlarında öğütülmüş yüksek fırın cürufu kullanılarak silindirle sıkıştırılmış beton üretimi gerçekleştirilmiştir. Üretilen silindirle sıkıştırılmış beton numunelerinin sıkıştırılabilme yüzdesi, birim hacim ağırlık, ultrases geçiş hızı, dinamik elastisite modülü, su emme, 3 ve 28 günlük beton basınç dayanımı değerleri tespit edilmiştir. Silindirle sıkıştırılmış betonlarda yüksek fırın cürufu kullanımıyla işlenebilirlik olumlu etkilenmiş, sıkıştırılabilme yüzdeleri artmıştır. Yüksek fırın cürufu ikamesi 3 günlük beton basınç dayanımlarında azalmaya neden olurken 28 günlük beton basınç dayanımlarında artış sağlamıştır.
