Beton Üretiminde Alternatif Sürdürülebilir Bağlayıcı: Çimento Yerine Kısmi Odun Külü Kullanımı

Öz

Çevre sorunlarının en aza indirilmesi için atık malzemelerin beton üretiminde kullanılması son zamanlarda oldukça teşvik edilmektedir. Portland çimentosu, CO2 emisyonlarına katkıda bulunan, yüksek enerji yoğun bileşenli bir malzemedir. Yerel atık malzemeler, eCO2 emisyonlarına katkıda bulunmayan daha kısa nakliye mesafeleri nedeniyle beton üretiminde trend oluyor. Odun külü, Kıbrıs'ta potansiyel olarak çöplük yoluyla bertaraf edilebilecek mevcut atıklardan biridir. Bu çalışma, 30 MPa ve 45 MPa'lık 28 d hedef tasarım dayanımları için %95 Portland çimentosu ve %5 odun külü ile yapılan beton karışımlarının çeşitli mühendislik özelliklerini (çökme, kütle yoğunluğu, basınç dayanımı, su geçirgenliği) performanslarını değerlendirmeyi amaçlamıştır. Ek olarak, laboratuvar karışımlarının çevresel (eCO2 emisyonları), ekonomik ve sosyal (termal iletkenlik ve ses geçirgenliği) açısından potansiyel sürdürülebilirlik performansını araştırmak için daha fazla değerlendirme yapılmıştır. Çökme, basınç dayanımı ve su geçirgenliğini içeren mühendislik özellikleri çalışmaları, WA karışımları için PC karışımlarına kıyasla benzer veya biraz daha iyi performans gösterirken, WA ilavesi kütle yoğunluğunu arttırdı. Sürdürülebilirlik performansı ile ilgili olarak, WA kullanımı, geleneksel karışımlara kıyasla eCO2 emisyonlarını azalttı. Sosyal sürdürülebilirlik göstergeleri, sürdürülebilir beton üretimi için umut verici bir yaklaşıma işaret eden WA karışımları için performansları da artırdı.

Alternative Sustainable Binder for Concrete Construction: Wood Ash as a Cement Replacement

Öz

The use of waste materials in concrete production has been highly encouraged recently to minimize the environmental problems. Portland cement is a high energy-intensive constituent material that contributes to CO2 emissions. Local waste materials are trending in concrete production due to shorter transportation distances that do not contribute to eCO2 emissions. Wood ash is one of the available wastes in Cyprus which is potentially disposed of through landfill. This study aimed to several various engineering properties (slump, bulk density, compressive strength, water permeability) performances of concrete mixes made with 95% Portland cement (PC) and 5% wood ash (WA) for 28 d target design strengths of 30 MPa and 45 MPa. In addition, further assessment was established to investigate the potential sustainability performance of the laboratory mixes from environmental (eCO2 emissions), economic and social (thermal conductivity and sound permeability) point of view. Studies of engineering properties, comprising slump, compressive strength and water permeability, showed either similar or slightly improved performances for WA mixes compared to PC mixes, while WA addition increased bulk density. Concerning sustainability performance, WA use decreased eCO2 emissions compared to conventional mixes. Social sustainability indicators had also enhanced performances for WA mixes indicating an encouraging approach for lower impact concrete production.
