Abstract

Light weight aggregate was produced by rapid sintering of red soil with some admixtures; i) sewage sludge for void formation, ii) sodium carbonate and fly ash for better sintering. Little cylinders were prepared with red soil to investigate the effect of a number of variables, including the fly ash ratio by weight of red soil (12% and 17%), pressing force (1, 3 and 5 KN), and rapid sintering temperature (1050 and 1100°C) on the physical and mechanical properties of light weight aggregate. Compressive strength increased with the increase in fly ash ratio. Considering the highest light weight aggregate specific strength (14,80 MPa / 0,98 ton/m3 = 15,10 kN.m/kg) the optimum production obtained with 17 % of fly ash, pressing with 1 kN and sintering at 1050°C.

Özet

Bu çalışmada Çöğürler/Kütahya’dan alınan kırmızı toprak; i) gözenek oluşturmak amacıyla evsel atık arıtma çamuru, ii) sinterleme özelliklerini iyileştirmek için sodyum karbonat ve uçucu kül eklenerek hızlı sinterleme yöntemi ile hafif agrega üretilmiştir. Küçük silindirler şeklinde üretilen hafif agregaların fiziksel ve mekanik özeliklerine; kırmızı toprağın ağırlıkça %’si olarak uçucu kül miktarı (%12 ve %17), presleme kuvveti (1, 3 ve 5 kN) ve sinterleme sıcaklığının (1050 ve 1100°C) etkisi araştırılmıştır. Uçucu kül miktarı arttıkça basınç dayanımda artış gözlenmiştir. En yüksek hafif agrega özgül dayanımı (14,80 MPa / 0,98 ton/m3 = 15,10 kN.m/kg) dikkate alınarak en uygun üretim %17 oranında uçucu kül kullanımı, 1 kN ile presleme ve 1050°C’de hızlı sinterleme ile elde edilmiştir.
