Mechanical Performance of Local Materials in Sustainable Construction in the Arid Region of Southwestern Algeria.

Abstract

The primary objective is to evaluate the impact of environmental parameters on the mechanical properties of BTS. Compression and flexural tests were conducted to measure their resistance under various conditions, such as water immersion, prolonged sun exposure, and high temperatures. The results show that these bricks meet resistance standards, with notable improvements after immersion in water or exposure to heat. However, prolonged exposure to humid soils reduces their performance. BTS represent a sustainable alternative to cement, which is commonly used but has a significant ecological impact. They help preserve traditional construction techniques, ensure better adaptation to Saharan climates, and strengthen the local architectural heritage. Moreover, the use of local materials like BTS stimulates the socio-economic development of Saharan regions. It promotes traditional know-how, creates jobs, and reduces dependency on imported materials. This approach thus contributes to environmental preservation, improves local living conditions, and enhances the sustainability of constructions in these regions. This research highlights the importance of BTS in reconciling heritage preservation, sustainable construction, and socio-economic development in Saharan environments.
