The Role of Recycled Materials in Sustainable Ground Improvement

Abstract

This study comprehensively evaluates the use of recycled materials within the scope of sustainable ground improvement techniques through an extensive literature review. Industrial wastes (fly ash, cement kiln dust, blast furnace slag), construction and demolition wastes (recycled concrete and asphalt aggregates), and other waste materials (tire granules, crushed glass) have been investigated for their efficacy in enhancing the geotechnical properties of soils. Research findings indicate that these materials lead to positive changes in soil characteristics such as plasticity, strength, swelling potential, and permeability. Furthermore, the utilization of these materials offers significant advantages in terms of environmental sustainability, including the reduction of carbon footprint, conservation of natural resources, and improved waste management. Economic analyses also demonstrate that recycled materials provide cost-effective solutions. This study aims to contribute to sustainable ground improvement practices by proposing recommendations for deepening research in this field, monitoring environmental risks, and developing relevant standards.

Sürdürülebilir Zemin İyileştirmede Geri Dönüşümlü Malzemelerin Rolü

Abstract

Bu çalışma, sürdürülebilir zemin iyileştirme teknikleri kapsamında geri dönüşümlü malzemelerin kullanımını kapsamlı bir literatür taraması ile değerlendirmektedir. Endüstriyel atıklar (uçucu kül, çimento fırın tozu, yüksek fırın cürufu), inşaat ve yıkım atıkları (geri dönüşümlü beton ve asfalt agregaları) ile diğer atık malzemeler (lastik granülleri, kırılmış cam) zeminlerin geoteknik özelliklerini iyileştirmede incelenmiştir. Yapılan araştırmalar, bu malzemelerin plastisite, dayanım, şişme ve geçirgenlik gibi zemin özelliklerinde olumlu değişikliklere yol açtığını ortaya koymaktadır. Ayrıca, bu malzemelerin kullanımı çevresel sürdürülebilirlik açısından karbon ayak izinin azaltılması, doğal kaynakların korunması ve atık yönetimi gibi önemli avantajlar sağlamaktadır. Ekonomik analizler ise geri dönüşümlü malzemelerin maliyet etkin çözümler sunduğunu göstermektedir. Çalışma, bu alandaki araştırmaların derinleştirilmesi, çevresel risklerin izlenmesi ve standartların geliştirilmesi yönünde önerilerde bulunarak sürdürülebilir zemin iyileştirme uygulamalarına katkı sağlamayı amaçlamaktadır.
