Resumen
In this study, earth blocks (EB) and compressed earth blocks (CEB) are fabricated and investigated along with the development of a mathematical model of compressive and tensile loads. The investigated specimens are manufactured from a mixture of soil, ground recycled concrete (GRC) powder and water in weight fractions of 4:1:1. EBs are molded and CEBs are obtained by quasi-static compression in wet state. Material samples extracted from the blocks are tested in dry state for compressive strength and three-point flexural strength according to ASTM standards. The results indicate that CEB exhibits 130% higher compressive load capacity and 63% higher tensile strength compared to EB. Furthermore, the proposed and calibrated mathematical model is able to adequately describe the strength and damage behavior of both materials. Finally, microstructural/micromechanical interrelationships with the modeled material response are established based on a characterization of postmortem CEB samples using EDS elemental analysis and SEM micrographs techniques. © 2023 Elsevier Ltd
