COMPARISON OF PHYSICAL AND MECHANICAL PROPERTIES OF COLD BONDED AND SINTERED LIGHTWEIGHT ARTIFICIAL AGGREGATES

Abstract

Artificial aggregate production which has the highest volume ingredient in concrete has gained great importance in recent years. The fundemental cause for this is to reduce harmful environmental impacts. In addition, artificial aggregates are tried to be used to improve some important features of concrete. In the present study, the physical and mechanical properties of two types of artificial aggregates produced by cold bonding and sintering methods were compared. For this purpose, artificial aggregates pelletized and sintered at different temperatures were produced by using fly ash at different percentages. Dry density, specific density, water absorption and crushing strength tests were carried out to investigate the physical and mechanical properties of the produced artificial aggregates. The results showed that the bulk density and density values of sintered Fly ash artificial aggregates have a trend of rising but the water absorption values have a decreasing trend. Moreover the highest crushed strength value was observed in samples sintered at 900 oC.

SOĞUK BAĞLAMA VE SİNTERLEME YÖNTEMİ İLE ÜRETİLMİŞ HAFİF YAPAY AGREGALARIN FİZİKSEL VE MEKANİK ÖZELLİKLERİNİN KARŞILAŞTIRILMASI

Öz

Beton içerisinde en yüksek hacme sahip olarak yer alan agregaların yapay olarak üretimi son yıllarda çok büyük bir önem kazanmıştır. Bunun başlıca sebebi zararlı çevresel etkileri azaltmaktır. Ayrıca betonun bazı önemli özelliklerini iyileştirmek için de yapay agregalardan faydalanılmaya çalışılmaktadır. Bu çalışmada soğuk bağlama ve sinterleme yöntemi ile üretilmiş iki tür yapay agreganın fiziksel ve mekanik özellikleri kıyaslanmıştır. Bu amaçla farklı oranlarda uçucu kül kullanılarak pelletlenmiş ve farklı sıcaklıklarda sinterlenmiş yapay agregalar üretilmiştir. Üretilen yapay agregaların fiziksel ve mekanik özelliklerini araştırmak için kuru yoğunluk, özgül yoğunluk, su emme ve ezilme mukavemeti deneyleri yapılmıştır. Sonuçlar sinterlenmiş uçucu küllü yapay agregaların yoğunluk ve özgül yoğunluk değerlerinin artan eğilimde ancak su emme değerlerinin azalan eğilimde olduğunu göstermiştir. Ayrıca en yüksek ezilme dayanımı 900 oC’de sinterlenmiş numunelerde gözlenmiştir.
