dc.description.abstractIN 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
