Abstract
Monuments and historical remains built of raw earth show that this material can persist for centuries. As with the cultural and historical heritage of the city of Rabat (Morocco), Chellah is one of the most historically significant monuments, this site being the melting pot of several civilizations that have played a major role, including the Marinid who left traces of Islamic architecture through the Medersa site built by the adobe construction technique.
This research involves the experimental and numerical analysis of the adobe material obtained from the Chellah site as well as the additive mixture in order to identify their mechanical behaviour. After the geotechnical identification of the material, a series of mechanical tests (compressive and bending tensile strengths) were applied to the adobe and the additive mixture. For numerical simulation, the finite element method was used to simulate the failure process of the material and different mixtures using the ANSYS software (ANSYS, 2019 1R). Numerical predictions are compared with experimental data. The methodology applied in this study provides promising results to better predict the mechanical properties of the mix used on the construction and rehabilitation of historic monuments in order to further reduce costly experimental tasks.
