Abstract

Geopolimerler silis ve alümina bakımından zengin toz malzemelerin yüksek alkaliniteye sahip çözeltilerle birlikte kullanılması ile üretilen çevre dostu yapı malzemeleridir. Farklı uygulamalar için geliştirilen kompozit malzemelerin çekme dayanımları ve enerji yutma kapasitelerini arttırmak için sürekli veya süreksiz liflerle matris fazının takviye edilmesi uzun yıllardır uygulanmaktadır. SIFCON kompozitler de bunlardan biri olup liflerin kalıba yerleştirilmesi ve devamında çok akıcı matris fazının lifler arasındaki boşluğu doldurması yöntemi ile üretilmektedir. Ancak geopolimer matrisin SIFCON üretiminde kullanımı hakkında araştırmalara ihtiyaç duyulmaktadır. Bu çalışmada hacimce %5 çelik lif içeren uçucu kül tabanlı geopolimer SIFCON kompozitler üretilmiş ve bunların eğilme dayanımları, basınç dayanımları ve tokluk özellikleri hem yüksek sıcaklığa maruz bırakılmamış, hem de 900°C etkisine maruz bırakılmış numuneler üzerinde incelenmiştir. Ayrıca, geopolimer SIFCON ile benzer eğilme dayanımına sahip çimento tabanlı geleneksel SIFCON kompozitler kıyaslama amacı ile kullanılmıştır. Çalışmanın sonucunda uçucu kül tabanlı geopolimer SIFCON’ların yüksek sıcaklık etkisi sonrasında çimento tabanlı SIFCON’lardan daha yüksek eğilme dayanımı ve tokluk değerlerine sahip olduğu tespit edilmiştir. Ayrıca benzer eğilme dayanımlarında geopolimer SIFCON’ların daha yüksek basınç dayanımına ulaştıkları görülmüştür.

Investigation of Flexural Strength and Toughness of Fly Ash Based Geopolymer SIFCON

Abstract

Geopolymers are environmentally friendly construction materials produced by the use of silica and alumina-rich powder materials with high alkaline solutions. Reinforcing the matrix phase with continuous or discontinuous fibers has been applied for many years to increase the tensile strength and energy absorption capacity of composite materials developed for different applications. SIFCON composites are one of them, and they are produced by placing the fibers in the mold and then filling the mold with very fluid matrix phase. However, there is a need for research on the use of geopolymer matrix in SIFCON production. In this study, fly ash-based geopolymer SIFCON composites containing 5% by volume steel fibers were produced and their flexural strength, compressive strength and toughness properties were investigated on both samples that were not exposed to high temperature and exposed to 900°C. In addition, cement-based conventional SIFCON composites with similar flexural strengths with the geopolymer SIFCON were used for comparison. It was determined that the fly ash-based geopolymer SIFCON had higher flexural strength and toughness values than that of the cement-based SIFCON after exposing to high temperature. In addition, for a given flexural strength, geopolymer SIFCON showed a higher compressive strength than that of conventional SIFCON.
