Abstract

Concrete, because of its brittle nature, is very prone to cracking especially under induced tensile stresses. Those cracks make the material vulnerable to external influences. Water penetrating through the cracks yields various durability issues that shorten the service life of the concrete. However, contrary to ordinary concrete, in Engineered Cementitious Composites (ECC) formation of multiple and tight micro-cracks under loading yields to high ductility, energy absorption capacity and durability. Besides, these tiny cracks also exhibit self-healing properties with the help of a high amount of binding materials available in composite composition. Within the scope of this study, in the design of the ECC, two different mixtures with low and high fly ash amounts were produce. Furthermore, waste materials of the Muğla region which cause environmental pollution and have little or no commercial value were used in ECC production. Mechanical strength values and self-healing properties of the specimens were investigated at the scope of the study.

Özet

Beton, gevrek yapısı nedeniyle, özellikle tetiklenmiş çekme gerilmeleri altında çatlamaya meyillidir. Bu çatlaklar malzemeyi dış etkenlere karşı savunmasız hale getirir. Çatlaklardan geçen su betonun ömrünü kısaltan çeşitli dayanıklılık sorunları doğurur. Ancak, normal betonun aksine, Tasarlanmış Çimentolu Kompozitlerde (TÇK), yükleme altında çok sayıda ve sıkı mikro çatlak oluşumu, yüksek süneklik, enerji yutma kapasitesi ve dayanıklılık sağlar. Ayrıca, bu küçük çatlaklar, bileşimde bulunan yüksek miktarda bağlayıcı malzeme yardımı ile kendi kendini iyileştirme özellikleri de sergiler. Bu çalışma kapsamında, ECC tasarımında, düşük ve yüksek uçucu kül miktarlarına sahip iki farklı karışım üretilmiştir. Buna ek olarak, Muğla bölgesinin çevre kirliliğine neden olan ve az veya hiç ticari değeri olamayan atık malzemeleri TÇK üretiminde kullanılmıştır. Çalışma kapsamında numunelerin mekanik dayanım değerleri ve kendi kendini iyileştirme özellikleri incelenmiştir.
