6. Physico-mechanical Characterizations of the Compressed Earth Block (CEB) Stabilized with Lime-Based Fibers (Waste Tyre Rubber-Glass)

To reduce construction costs and energy consumed in the heating and air conditioning, one of the solutions is to use the fiber to install Compressed Earth Blocks (CEB). The main purpose of this work is to study the effect of using the scrap tyre rubber fiber and the glass fiber on the mechanical properties and behavior of the CEBs. In this context, we used a lime ratio of (12%) and six fiber percentages (0.05, 0.1, 0.15, 0.20, 0.25 and 0.30%) from dry mixture. The results indicate that the compressive and shear strengths increase proportionally with the fiber ratio until a maximum at the ratios 0.15% for the scrap tyre rubber fiber, and 0.20% for the glass fiber, and then begin to decrease. However, the presence of the fiber has a positive impact on the mechanical behavior of the composite. This study also showed that monitoring of increased stress has a positive impact on the different studied characteristics.
