Natural aging of wood in historic wooden buildings: Literature review

Abstract

Wood has been used for centuries as the only renewable construction material, standing out with its high strength relative to its weight, workability, durability, and natural aesthetic qualities such as color and texture. The objective of this study is to examine the process of natural aging in wood by reviewing existing literature and to identify how this aging process influences the material’s chemical, physical, and mechanical properties. Nowadays, the scarcity of data on naturally aged wood and the common attempt to overcome this limitation by using accelerated aging samples highlight the importance of this study. In recent years, researchers working to protect our planet have increasingly focused on the preservation, recycling, and reuse of wood, which is recognized as a sustainable building material. Reviewing the natural aging of wood based on scientific data will help extend its service life and encourage new research.

Tarihi ahşap yapılarda ahşabın doğal yaşlanması: Kaynakların incelenmesi

Abstract

Ahşap, yenilenebilir tek yapı malzemesi olması nedeniyle yüzyıllar boyu kullanılmış, ağırlığına oranla taşıma gücünün yüksek olması, kolay işlenebilmesi, dayanıklılığı, doğal renkleri, dokusu gibi birçok özelliği ile ön plana çıkmıştır. Çalışmada amaç ahşabın doğal yaşlanmasına ait literatürdeki verileri inceleyerek yaşlanma sürecini tanımlamak ve yaşlanmanın ahşabın kimyasal, fiziksel ve mekanik özellikleri üzerine etkilerini ortaya koymaktır. Günümüzde doğal yaşlanmış ahşaba ait verilerin oldukça sınırlı olması ve genelde hızlandırılmış yaşlanmış örneklerle bu eksikliğin giderilmeye çalışılması bu çalışmanın önemini ortaya koymaktadır. Sürdürülebilir bir yapı malzemesi olan ahşabın yerinde korunması, geri dönüşümü ve/veya yeniden kullanımı da gezegenimizi korumak için çalışan araştırmacıların son yıllarda yoğunlaştığı konulardır. Bilimsel verilere dayanarak ahşabın doğal yaşlanmasının gözden geçirilmesi, ahşabın kullanım ömrünü uzatmaya yardımcı olacak ve yeni araştırmaları teşvik edecektir.
