Abstract

In this study the effect of aggregate type on some properties of fly ash- and waste brick powder-based geopolymers was investigated comparatively. In this context, unit weight, compressive strength, and high-temperature resistance of geopolymer mortars prepared with pumice aggregate and standard CEN sand were examined. In the preparation of mortars, the brick powder obtained by grinding waste bricks, Class F fly ash, sodium silicate and sodium hydroxide were used. A laboratory-type oven and a household microwave oven were used for curing. Oven and microwave curing were applied at 90°C for 48 hours and at 300-watt power level for 20 (for fly ash) or 30 (for brick powder) minutes, respectively. It was determined that the aggregate type significantly affects the geopolymer mortar properties. Regardless of the aluminosilicate and aggregate type, higher compressive strengths were achieved with oven curing, and the compressive strengths of the mortars produced with pumice aggregate were lower than those of the mortars prepared with CEN sand. On the other hand, microwave curing was more advantageous in terms of high-temperature resistance. Oven-cured mortars lost strength upon exposure to the high temperature, but the compressive strength of mortars subjected to the microwave curing generally increased after exposure to high temperatures.

Agrega türünün uçucu kül ve tuğla tozu esaslı geopolimer harç özelliklerine etkisi

Abstract

Bu çalışmada, kum türünün uçucu kül ve atık tuğla tozu esaslı geopolimerlerin bazı özellikleri üzerindeki etkisi araştırılmıştır. Bu kapsamda pomza agregası ve CEN standart kumu kullanılarak üretilen geopolimer harçların birim hacim ağırlık, basınç dayanımı ve yüksek sıcaklık dirençleri incelenmiştir. Harçların üretilmesinde, defolu tuğlaların öğütülmesi ile elde edilen tuğla tozu, F sınıfı uçucu kül, sodyum silikat ve sodyum hidroksit; harçların kürlenmesinde ise laboratuvar tipi hava dolaşımlı etüv ve ev tipi mikrodalga fırın kullanılmıştır. Etüv küründe, numuneler 48 saat boyunca 90°C’de kürlenirken mikrodalga küründe 300 watt güç seviyesinde, uçucu kül için 20 dakika, tuğla tozu için 30 dakika kürleme yapılmıştır. Alüminosilikat ve agrega türünden bağımsız olarak, etüv kürü ile daha yüksek basınç dayanımlarına ulaşıldığı, pomza agregası ile üretilen harçların basınç dayanımlarının, CEN kumu kullanılan harçlardan daha düşük olduğu belirlenmiştir. Buna karşın, yüksek sıcaklık direnci bakımından mikrodalga kürünün daha avantajlı olduğu, etüv kürü ile üretilen harçların yüksek sıcaklık etkisi ile dayanım kaybı yaşadıkları ancak mikrodalga kürü uygulanan harçların yüksek sıcaklıklara maruz kaldıktan sonra basınç dayanımlarının genel olarak yükseldiği belirlenmiştir.
