Abstract

In this study, geopolymer mortars were produced with alkali activated the waste powders obtained by grinding of the defective / discarded products generated during the production of vitrified (ceramic sanitaryware) products. The effect of different liquid / binder ratio and activator molarity was investigated on the produced mortars. To achieve this goal, geopolymer mortars were prepared with liquid:binder ratios of 0.45, 0.50 and in four different molarities as 10, 12, 14 and 16 M NaOH. The produced mixtures were cured in oven at 80℃ for 24 h then in air for a period 28 days. The workability, unit weight, flexural and compressive strength, water absorption and volume of permeable voids ratio tests were performed on mortar samples. While the liquid:binder ratio of the samples is 0.50, the increase in molarity was not have a positive effect on mechanical properties, but improved the workability. When the liquid:binder ratio is 0.45, the increase in molarity showed a significant improvement in the strength and approximately 34 MPa compressive strength was obtained at 16 M NaOH concentration. However, in terms of improved strength, environmental and economic conditions, it has been determined that the appropriate molarity for geopolymer mortar production is 12 M at 0.45 in liquid:binder ratio.

Özet

Bu çalışmada, seramik sağlık gereci (vitrifiye) üretimi esnasında ortaya çıkan hatalı/ıskarta ürünlerin öğütülmesi ile elde edilen atık tozlar alkali ile aktive edilerek geopolimer harçlar üretilmiştir. Üretilen harçlara farklı sıvı/bağlayıcı oranı ve aktivatör molaritesinin etkisi araştırılmıştır. Bu amaçla sıvı bağlayıcı 0,45 ve 0,50 oranlarında 10, 12, 14 ve 16 M NaOH çözeltilerinde karışımlar hazırlanmıştır. Üretilen harç karışımlarına 80°C’de 24 saat ısıl kür ve 28 güne kadar havada kür uygulanmıştır. Numunelere işlenebilirlik, birim ağırlık, eğilme ve basınç dayanımı, su emme ve boşluk oranı deneyleri uygulanmıştır. Numunelerin sıvı/bağlayıcı oranı 0,50 iken molaritenin artması mekanik özelliklere olumlu etkisi olmamakta ancak işlenebilirliği iyileştirmektedir. 0,45 sıvı/bağlayıcı oranında ise molaritenin artışı dayanımda önemli gelişme göstererek 16 M NaOH konsantrasyonunda yaklaşık 34 MPa basınç dayanımı elde edilmiştir. Ancak artan dayanım, çevresel ve ekonomik koşullar açısından geopolimer harç üretimi için uygun molaritenin sıvı/bağlayıcı oranı 0,45’de 12 M NaOH olduğu belirlenmiştir.
