Modern research is focused on the discovery of new compounds that meet the requirements of modern construction. An example of low energy consumption is that buildings consume between 20% and 40% of energy. In this research, the effect of fiber addition on the properties of compacted earth bricks composed of clay and sand and fixed with cement is studied. Fiberglass or palm are used in different proportions (0% and 0.4%). This is done by studying the change in mechanical and thermal properties. The study focuses on clarifying the role of fiber type and the amount of compressive force applied to the soil. To change the properties of bricks. This is studied using experimental methods and systematization criteria. The results showed a decrease in density by 9.1%, with a decrease in water absorption by 8%, an increase in brick hardness by 42.7%, and a decrease in thermal conductivity by 22.2%. These results show that the addition of fiber improves mechanical and thermal properties. Which reduces energy consumption. The results are important because they explain the changes that occur in the earth block when palm fibers and glass are added and how they are used to improve earthen buildings.

This study aims to preserve and improve the durability of earthen buildings in rural areas of Morocco, particularly in the Al Haouz province of the Marrakech-Safi region. In this paper, a survey was conducted to identify defects in earthen building materials and investigate factors that lead villagers to use cement over traditional earth-based construction methods. To propose solutions to these shortcomings, mineralogical, physicochemical, and geotechnical studies were conducted on four soils commonly used as rural building materials. Subsequently, some corrections were implemented in the treatment of raw materials and the production process of compressed earth blocks (CEBs), which were then subjected to mechanical, physical, and morphological characterization. The findings of this study revealed several building pathologies in earthen construction in this region, including ceiling water leaks, formulations made, and cracks. Research shows that the key factors influencing the durability of building materials are particle size distribution, mineralogy composition, moisture content, and con-struction process.
