the mechanical and thermal properties of the reinforced earth depend upon both fiber content and earth type. The internal meso-structure, porosity and fiber networking clearly influence the overall mechanical and thermal performance of the composites. Ongoing research is focusing on the numerical analysis of these results from both mechanical and thermal standpoints. Transient heat-based models with mechanical constraints will be developed using the above experimental data as a benchmark. The primary objective will be to assess the validity of a meso-to-macroscopic homogenizing model for predicting the thermo-mechanical behavior of earth-based materials, thus leading to the best recipe for building scale applications.
