Abstract

This review paper delves into the innovative realm of self-healing concrete as a sustainable solution in the construction industry. The paper critically examines the development and application of self-healing concrete, particularly focusing on its capacity to autonomously repair cracks and microfractures, thereby enhancing structural durability and reducing environmental impact. The review highlights the application of microbial methods, especially the use of bacteria such as Bacillus sp., in facilitating the repair process in an environmentally friendly manner. It explores the mechanisms of self-healing concrete, its sustainability benefits including prolonged lifespan of structures, reduced maintenance requirements, and decreased carbon emissions. However, the paper also addresses the challenges and limitations associated with the technology, such as the efficacy of bacteria over long-term applications and cost considerations. Furthermore, the manuscript provides insights into practical applications and case studies of self-healing concrete, showcasing its effectiveness in real-world scenarios. The incorporation of Life Cycle Assessment (LCA) in evaluating self-healing concrete is discussed, offering a comprehensive understanding of its environmental impact throughout its life cycle. Despite the challenges, the potential benefits of self-healing concrete are emphasized, positioning it as a promising avenue for sustainable construction practices in the context of growing global demand for concrete and the need for environmentally conscious solutions.

Sürdürülebilir İnşaat için Kendiliğinden İyileşen Betonun Geliştirilmesindeki İlerlemeler ve Zorluklar - Eleştirel Bir İnceleme

Abstract

Bu inceleme makalesi, inşaat sektöründe sürdürülebilir bir çözüm olarak kendiliğinden iyileşen betonun yenilikçi alanına derinlemesine bir bakış atar. Makale, özellikle çatlakları ve mikro çatlakları otonom olarak onarma kapasitesine odaklanarak, kendiliğinden iyileşen betonun geliştirilmesi ve uygulanmasını eleştirel bir şekilde inceler, bu da yapısal dayanıklılığı artırır ve çevresel etkiyi azaltır. İnceleme, özellikle Bacillus sp. gibi bakterilerin kullanımı aracılığıyla, tamir sürecini çevre dostu bir şekilde kolaylaştıran mikrobiyal yöntemlerin uygulanmasını vurgular. Kendiliğinden iyileşen betonun mekanizmalarını, sürdürülebilirlik faydalarını, yapıların ömrünün uzamasını, bakım gereksinimlerinin azalmasını ve karbon emisyonlarının azalmasını araştırır. Ancak, makale aynı zamanda teknolojiyle ilişkili zorlukları ve sınırlamaları da ele alır, örneğin uzun süreli uygulamalarda bakterilerin etkinliği ve maliyet hususları gibi. Ayrıca, el yazması, kendiliğinden iyileşen betonun gerçek dünya senaryolarındaki etkinliğini sergileyen pratik uygulamalar ve vaka çalışmaları hakkında bilgiler sunar. Kendiliğinden iyileşen betonun değerlendirilmesinde Yaşam Döngüsü Değerlendirmesi'nin (LCA) dahil edilmesi tartışılmakta olup, bu da onun çevresel etkisine yaşam döngüsü boyunca kapsamlı bir anlayış sunar. Zorluklara rağmen, kendiliğinden iyileşen betonun potansiyel faydaları vurgulanmakta ve artan küresel beton talebi ve çevre bilinçli çözümlere duyulan ihtiyaç bağlamında sürdürülebilir inşaat uygulamaları için umut verici bir yol olarak konumlandırılmaktadır.
