A key advantage of plastic lies in its promising mechanical properties. Concrete mix design is fundamental to a wide range of construction applications, including brick walls, reinforced concrete slabs and concrete pavements. Despite the adoption of recycled plastic in construction materials in various countries, its widespread implementation remains limited. This is primarily due to …

The Philosophy Of Selling Community: Developer Narratives And Resident Experiences Of Privacy And Community In Gated Communities In Cairo, Yosr Samir Raghib

Theses and Dissertations

Gated communities have become a global urban form with diverse impacts on their inhabitants. In recent years, Cairo has been expanding to the edges, and land that has always been a desert is now rapidly transforming into new cities that people are leaving their homes in the center of the city to move to seeking seclusion, security, privacy, and sense of community. Despite the tension proven between privacy and community, developers attempted to sell both concepts to coexist in gated communities in different manners to express their unique brand. Both concepts are defined differently by each developer, resulting in different …
