Go to Editorial ManagerThe strategy of reusing materials and architectural elements in new buildings and locations after extracting them from previous structures and sites, known historically as "spolia," is now an important approach in contemporary architectural project design. This strategy showcases a balance between tradition and innovation, transforming heritage elements into new architectural pieces that carry contemporary artistic and cultural values. The purpose of this research is to uncover the forms of this practice and the meanings or purposes associated with it, within a theoretical framework that serves as a tool for designers when dealing with such projects. The research reviews studies on the subject and extracts the most important terms, then moves on to analyse several worldwide case studies of contemporary projects that have applied the concept of spolia reuse. The purpose is to enrich the framework by highlighting the reused architectural elements and their new functions, as well as the meanings and interpretations linked to these cases. The research identifies key indicators, including respect for heritage, creative artistic expression, sustainability, and recycling. The aim of the article is to shed light on the importance and effectiveness of using the concept of spolia reuse in the design of modern architectural projects and to promote a sustainable and innovative architectural culture.
In term of sustainable practices, recycling plays a crucial role, particularly in the construction industry where the disposal of old structures generates significant waste. Recycling old concrete not only reduces the need for new natural resources but also eliminate waste accumulation. Numerous research study the behaviors of recycled aggregate concretes, practically focusing on the long term behaviours. A large number of studies have demonstrated that concrete made from recycled aggregate exhibits poorer long-term characteristics in comparison to aggregate from nature concrete. The long-term behaviour can be affected by three factor which is creep, shrinkage and tension stiffening. Greater management of these variables can enhance the RAC's long-term properties. The review will specifically focus on the influence of time dependent parameters i.e., creep, shrinkage, and loss of tension stiffening with time. Furthermore, it will explore the long-term deflection predicted from code used for deflection prediction, considering three codes: ACI, EC2, and the CSA code. The purpose of this paper is to enhance the understanding of long-term deflection of recycled aggregate concrete beam and evaluate the effectiveness of various factors that impact their structural performance.
Plastic pollution represents a significant global environmental challenge, with millions of tons of plastic waste accumulated annually in landfills and natural ecosystems. The COVID-19 pandemic intensified this issue due to the widespread use of single-use personal protective equipment. As a response to this problem, this study examines the use of recycled polyethylene terephthalate and single-use face masks as additives in porous asphalt mixtures to improve the mixtures’ properties and promote sustainability in pavement engineering. The research aimed to evaluate the combined effect of incorporating recycled polymers into a hybrid system, rather than separately modified mixtures of polyethylene terephthalate and single-use face mask fibers. Laboratory tests indicated that the hybrid mixture exhibited optimal performance, achieving a 34% increase in Marshall stability, a 19% decrease in flow, and a 20% reduction in air-void content. Additionally, permeability decreased by 36%, while remaining within the accepted limit, improving moisture susceptibility, and cantabro abrasion losses decreased by up to 11%, suggesting improvements in cohesion, structure, and durability. The findings demonstrate that hybrid polymer modification offers an environmentally sustainable and high-performance approach for future porous asphalt pavements.
