Abstract

In this investigation, the strength properties of the lightweight mortars made with waste PET aggregates and slag were examined. There were two different PET-binder ratio 0.50 and 0.60 used to produce mortar mixtures. Waterbinder ratios were chosen as 0.45 and 0.50. Normal Portland Cement and Granulated Blast-Furnace Slag (GBFS) were used as the binder. The GBFS mixtures obtained by GBFS replacing the cement on mass basis at the replacement ratio of 50 %. The test results showed that the mortar samples made with waste PET aggregates may be utilized as structural lightweight concrete depending on the strength properties. The increase in PET-binder ratio from 0.50 than 0.60 did not reduce the compressive strength of the samples. The decrease in w/b ratio from 0.50 than 0.45 increased in the compressive and flexural tensile strengths.

Özet

Bu çalısmada, atık PET agregalı ve cüruflu hafif haçların dayanım özellikleri incelenmistir. Harç karısımların üretiminde 0.50 ve 0.60 olmak üzere iki PET-bağlayıcı oranı kullanılmıstır. Su-bağlayıcı oranları 0.45 ve 0.50 olarak tespit edilmistir. Bağlayıcı olarak Portland Çimentosu ve yüksek fırın cürufu kullanılmıstır. Cüruflu karısımlar, yüksek fırın cürufunun çimentoyla ağırlıkça %50 oranında yer değistirilmesiyle elde edilmistir. Gerçeklestirilen deneyler sonucunda, atık PET agregalı harç numunelerin dayanım özellikleri göz önüne alınarak, tasıyıcı hafif beton sınıfına girebileceği ortaya çıkmıstır. PET/B oranının 0.50’den 0.60’a çıkması, basınç dayanım değerlerinde düsmeye sebep olmamıstır. S/B oranının 0.50’den 0.45’e düsmesiyle, PET agregalı hafif harçların basınç ve eğilme dayanım değerleri yükselmistir.
