KÜRLEME SICAKLIĞI VE SU İÇERİĞINİN GENLEŞTİRİLMİŞ PERLİT İÇEREN HAFİF JEOPOLİMERLERİN ÖZELLİKLERİNE ETKİSİ

Abstract

Son yıllarda hafif beton üretimi önemli ölçüde gelişmiştir. İnşaat ve altyapıdaki önemi nedeniyle dünya çapında tüketimi gün geçtikçe artmaktadır. Hafif beton teknolojisindeki önemli bir ilerleme, endüstriyel olarak üretilen hafif agregaların geliştirilmesi olmuştur. Hafif beton, yapılarda ölü yüklerin azalması ve Portland çimentosuna kıyasla daha etkili bina yalıtımı gibi çeşitli avantajlar sunmaktadır. Ek olarak, jeopolimerler gibi sürdürülebilir yapı malzemeleri, Portland çimentosu üretimiyle ilişkili ekolojik sorunları çözmek için kullanılmaktadır. Hafif jeopolimer beton iki yaklaşımın avantajlarını birleştirir. Bu karışımlar, düşük özgül ağırlıklı doğal veya sentetik agregaların alüminosilikat bağlayıcılar ve alkali bir çözelti ile karıştırılmasıyla üretilebilirler. Bu çalışmada, alumina silikat kaynağı olarak uçucu kül ve ağırlıkça CEN standart kumunun kısmi ikamesi olarak genleştirilmiş perlit kullanılarak jeopolimer numuneleri üretilmiştir. Genleştirilmiş perlit kullanılarak hafif jeopolimerlerin üretimi ve üretim koşullarının jeopolimerlerin mekanik ve mikroyapısal özellikleri üzerindeki etkileri araştırılmıştır. Farklı su miktarlarının ve farklı kürleme sıcaklıklarının jeopolimer numunelerinin özelliklerine olan etkileri incelenmiştir. Araştırma sonuçları, özellikle 70°C kürleme sıcaklığında ve belirli bir su miktarında (15 cm akış çapı elde etmek için) genleştirilmiş perlit kullanımının, mekanik özellikleri korurken yoğunluğu önemli ölçüde azalttığını ve referans numunenin yaklaşık %75'i kadar kabul edilebilir bir basınç dayanımı elde edilmesini sağladığını ortaya koymuştur. Bu durum, sürdürülebilir uygulamaları destekleyen etkili, hafif bir jeopolimer harç elde edilmesini sağlamıştır.

THE EFFECT OF CURING TEMPERATURE AND WATER CONTENT ON THE PROPERTIES OF LIGHTWEIGHT GEOPOLYMERS CONTAINING EXPANDED PERLITE

Abstract

In recent decades, lightweight concrete production has undergone significant development, and its consumption is increasing worldwide due to its importance in construction and infrastructure. A significant advancement in lightweight concrete technology was the development of industrially manufactured lightweight aggregates. Lightweight concrete offers several advantages, including reduced dead loads in structures and more effective building insulation compared to OPC. Additionally, sustainable building materials, such as geopolymers, are used to address ecological problems associated with the production of Portland cement. Lightweight geopolymer concrete combines the advantages of the two approaches. They can be produced by mixing low-specific-gravity natural or synthetic aggregates with aluminosilicate binders and an alkaline solution. In this study, geopolymer samples were produced using fly ash as an aluminosilicate precursor and expanded perlite as a partial replacement for the CEN standard sand by weight. The production of lightweight geopolymers using expanded perlite and the effects of production conditions on the mechanical and microstructural properties of the geopolymers were investigated. Geopolymer samples were produced using different water amounts and cured at different curing temperatures, and their effects on the properties were investigated. Findings revealed that using expanded perlite, particularly at 70°C curing temperature and a specific water amount (to obtain a flow diameter of 15 cm), significantly decreased density while maintaining mechanical properties by obtaining acceptable compressive strength, approximately 75% of that of the reference sample, resulting in an effective lightweight geopolymer mortar that supports sustainable practices.
