This study investigates the technical, legal, and organizational considerations involved in implementing investments under elevated transportation routes in European cities, with a particular focus on a case study of Switzerland. Over a three-week research period, ten unique projects situated beneath elevated transportation routes were analyzed, incorporating field research, documentation studies, surveys, and legal consultations. The findings shed light on the effectiveness of various solutions in executing such projects, offering valuable insights for architectural and urban design disciplines. The research underscores the importance of addressing contemporary challenges associated with modernizing and expanding transportation infrastructure in urban areas. By emphasizing the design of centrally located elevated transportation routes, especially railways, the study advocates for the creation of more sustainable and integrated urban spaces. Key themes include sustainable urban development, transportation infrastructure, urban planning, legal frameworks, and spatial resources. The choice of Switzerland as a case study reflects its reputation for effectively integrating transportation infrastructure with the urban environment, providing inspiration for innovative infrastructure projects worldwide.

Dharavi is world’s one of the densest slum settlements nestled within the city of Mumbai, India. Despite several redevelopment attempts, preserving the socio-cultural fabric and circular economy has remained a challenge. This paper endeavors to address this challenge by understanding the challenges and propose some design solutions tailored to this unique context. For this project, evolution of Dharavi is studied drawing parallels with squatter settlements in Mexico, distinguishing features of what may be termed as the 'slum of hope' versus the 'slum of despair'. Through meticulous activity mapping, we aim to understand the dynamics of various user groups within Dharavi, thereby informing the design of inclusive urban spaces. Furthermore, by examining housing case studies, we try to foster a more equitable distribution of resources and opportunities within Dharavi, while respecting and preserving its rich socio-cultural identity. This research not only contributes to the discourse on slum redevelopment but also offers practical insights and methodologies that may be applicable to similar contexts globally. By balancing the imperatives of urban development with the preservation of community identity, we strive to create a blueprint for sustainable and inclusive urban regeneration in Dharavi and beyond.

In the face of the escalating global issue of non-biodegradable industrial waste, this research pioneers an innovative solution by repurposing waste materials in road construction, offering a trifecta of benefits: recycling, economic viability, and ecological sustainability. Focusing on red mud, blast furnace slag, and lime production waste, the study explores nine formulations, revealing that a blend with 40% red mud, 35% blast furnace slag, and 8% lime production waste attains peak strength. Over time, these materials exhibit a remarkable strength increase: from 0.67-3.56 MPa at 3 days to 8.12-14.21 MPa after 365 days, meeting Kazakh regulations. Crucially, the developed road base materials demonstrate durability and environmental responsibility, devoid of heavy metal contamination. This research not only emphasizes the superiority of waste-derived materials but also employs advanced analytical techniques (X-ray diffraction, X-ray fluorescence, microscopy) to unravel their chemical and mineral composition, reinforcing the case for their adoption. The study underscores the sustainable use of industrial waste, mitigating landfill issues, and advocates for the widespread adoption of these road base materials that align with stringent environmental regulations, ensuring a resilient and eco-friendly infrastructure.

As the main building material, concrete brings with it certain problems like wear and tear and cracks. To address these issues, self-healing concrete (SHCr) has emerged as a promising solution. This paper aims at presenting a literature review on SHCr, with a specific focus on sodium silicate (SS) as the healing agent. SS, also referred to as water glass, exhibits significant promise in starting chemical reactions within the concrete matrix that result in self-healing phenomena. The integrated system of SHCr to repair cracks by itself not only enhances its durability but also significantly reduces maintenance expenses, thereby making it a reassuringly cost-effective solution. The autogenous, biological, and capsule-based healing processes that result in this self-repair process include the following: The importance of developing SHCr relates to prolonged durability of concrete structures with reduced intervention. SHCr, based on SS, exhibits the potential to strengthen the durability and sustainability of constructed environments for various domains such as infrastructure construction, green buildings, and marine construction. This article demonstrates that material composition, environment, and structural geometry are the significant attributes affecting SHCr. As was previously mentioned, self-repair concrete does have certain drawbacks, such as a high initial cost that this research seeks to significantly lower. These restrictions can also be overcome by combining the efforts of academics, professionals in the infrastructure-construction sector, and legislators in a cross-disciplinary manner. Lastly, the goal of this paper is to add to the body of knowledge already available on SHCr by elucidating the ways in which SS can enhance the healing properties of concrete systems and promote sustainability.

It can be argued that an ideal house is one that is large in scale, offering a sense of comfort and tranquillity, offering abundant and constant water and energy. Consequently, it is possible to install mini-scale gravity power plants under the building. These power plants can have turbines that operate continuously without requiring any external forces, functioning automatically and with high energy efficiency. They provide residents with essential services, including lighting, energy, water, and car charging. According to these explanations, our dream house can be located anywhere in the world, including underwater. It can be said that this power plant is utilized under the structure, and the building provides all the basic necessities to the residents freely and abundantly. It can be stated that the constant movement of gravitational fluxes in objects is similar to a raging river, which has the ability to move objects. This system enables the movement of special gravity turbines and generators, thus allowing the generation of sufficient and necessary electrical power.

Lightweight concrete suffers low strength and high volumetric changes due to the differences between density and elastic modulus between lightweight aggregate and cement paste. This paper presents a study on the physical and mechanical properties of lightweight concrete with density below 800 kg/m3 incorporating polypropylene fibers. Nine lightweight concrete mixes were prepared and tested in order to evaluate the influence of different fibers types and content on the performance of the developed material. Mechanical properties include compressive and flexural strength were measured, where physical properties include density, thermal conductivity and drying shrinkage were determined. The experimental results revealed that lightweight concrete with compressive strength of 14 MPa and flexural strength of about 3 MPa has been developed for some mixes which can be used for structural applications. On the other hand, thermal insulation depends mainly on the density of concrete. The use of polypropylene fiber has significant influence in reducing drying shrinkage and improving flexural strength.
