Bu çalışmada, perlit (PT) ve uçucu kül (UK) bazlı geopolimerlere çömlek sırı atığı (ÇSA) ikamesinin mekanik özellikler ve yüksek sıcaklık performansı üzerindeki etkisi araştırılmıştır. Sadece PT, sadece UK ve ağırlıkça %75 UK ve %25 PT içeriği ile üretilen geopolimer harçlara %10, 20 ve 30 oranlarında ÇSA ikame edilmiştir. Harçlar, sabit 10M NaOH içeriği ve 8 saat 100 ºC ısıl kür ile üretilmiştir. Üretilen harçların 7, 28 ve 90 günlük eğilme ve basınç dayanımları belirlenmiş ve 500 ºC, 750 ºC ve 1000 ºC sıcaklıklarındaki performansları değerlendirilmiştir. Deneyler sonucunda, ÇSA malzemesinin PT ve UK+PT içeren numunelere kütlece %20 oranına kadar ikame edilmesinin nihai basınç dayanımı açısından olumlu yönde etkileri olduğu, UK içeren numunelerde ise ÇSA ikamesinin nihai basınç dayanımı açısından olumsuz etkileri olduğu tespit edilmiştir. Nihai dayanımlarda en yüksek değerler, 34.4 ve 32.41 MPa basınç ve 6.46 ve 6.3 MPa eğilme dayanımları ile UK+PT+ÇSA içeren numunelerde sırasıyla %10 ve 20 ÇSA oranlarında elde edilmiştir. Eğilme ve basınç dayanımları açısından optimum ÇSA oranının %10-20 aralığında olduğu söylenebilir. UK malzemesine ÇSA malzemesinin ikamesi, kür yaşına göre dayanım gelişimlerini olumsuz etkilerken, PT ve UK+PT içeren numunelere ÇSA malzemesi ikamesi dayanım gelişimlerinde olumlu etkiler meydana getirmiştir. ÇSA malzemesi yüksek sıcaklık performansı açısından tüm gruplarda olumlu etki meydana getirmiştir. ÇSA malzemesinin karışımlarda kütlece ikame yüzdesi arttıkça, dayanım kayıpları azalmıştır. UK malzemesinin yerine %30 ÇSA malzemesinin ikame edildiği numunelerde 750 ºC’de %40’a varan dayanım artışı tespit edilmiştir.

THE EFFECT OF POTTERY GLAZE WASTE SUBSTITUTION ON HIGH-TEMPERATURE RESISTANCE OF FLY ASH AND PERLITE-BASED GEOPOLYMER MORTARS

Öz

In this study, the effect of substituting pottery glaze waste (PGW) into perlite (PT) and fly ash (FA) based geopolymers on mechanical properties and high-temperature performance has been investigated. Geopolymer mortars were produced with only PT, only FA, and a mixture of 75% FA and 25% PT by weight. PGW was substituted in these geopolymers at rates of 10%, 20%, and 30%. The mortars were produced with a constant 10M NaOH content and subjected to an 8-hour thermal curing at 100 ºC. The flexural and compressive strengths of the produced mortars were determined at 7, 28, and 90 days, and their performance at temperatures of 500 ºC, 750 ºC, and 1000 ºC was evaluated. As a result of the experiments, it has been determined that substituting PGW in specimens containing PT and FA +PT up to 20% by weight has a positive effect on the ultimate compressive strength. However, in samples containing FA, the substitution of PGW has been found to have negative effects on the ultimate compressive strength. The highest values in strengths were achieved in samples containing FA+PT+PGW, with compressive strengths of 34.4 and 32.41 MPa, and flexural strengths of 6.46 and 6.3 MPa, respectively, at PGW substitution rates of 10% and 20%. It can be stated that the optimum PGW substitution rate is in the range of 10-20% in terms of flexural and compressive strengths. Substituting PGW material into FA adversely affects strength development based on curing age, while substituting PGW material in samples containing PT and FA+PT has positive effects on strength. The PGW material has had a positive effect on high-temperature performance in all groups. As the mass substitution percentage of PGW material increased in the mixtures, strength losses decreased. In samples where 30% of the FA material was substituted with PGW, a strength increase of up to 40% was observed at 750 ºC.
