This work presents the physical-mechanical properties of two types of H-10 blocks of six holes fabricated in two different companies in Norte de Santander, Colombia to provide a general visualization of the ceramic properties of masonry products base clay. Random samples of H-10 blocks were collected from the selected companies directly from the furnace as part of the experimental procedure, which was used to perform the physical-mechanical tests such as initial and final water absorption, morphology, resistance to compression, and flexion according to the NTC 4017 standard procedure, the results obtained were compared with the values established in the NTC 4205 standard procedure, used as non-structural masonry products for indoor or outdoor use. Finally, the SEM-EDS micrographs exposed the maincharacteristic chemical elements (Al, Si, O), defects on the surface of an H-10 block and the presence of typical phases (Quartz, Kaolinite, Illite, and Hematite) obtained by the XRD technique.
