Abstract:

The construction industry continually seeks innovative solutions to enhance efficiency, reduce construction time, and improve structural performance. Lightweight sandwich wall panels have emerged as a promising technology addressing these needs. Lightweight wall panels are engineered materials that offer reduced density compared to traditional building components, without compromising strength and durability. These wall panels offer a wide range of benefits, such as ease of installation, reduced transportation costs, and improved thermal performance. Compared to traditional buildings, the density of sandwich wall panels is low. This study focuses on lightweight sandwich wall panels, which consist of two outer layers (face layer) and an inner layer (inner core). The facings can be made from materials such as fiber-reinforced polymer, high-strength concrete, ferrocement or steel, while the core is typically composed of lightweight materials like foam concrete, expanded polystyrene (EPS), or autoclaved aerated concrete (AAC). In this project, the face layer is made up of ferrocement, and the inner core is made up of foam concrete. These panels contribute to energy efficiency by providing insulation and reducing the overall impact on the buildings.
