Resistencia a la compresión de adoquines de hormigón. Resultados tendientes a validar el ensayo en medio adoquín

With the purpose of validating the compressive strength test result on half-unit specimen for concrete paving blocks quality control, experimental results on half-unit and whole unit blocks from 24 production batches were analyzed. The compressive strength results in whole unit was greater than in half-unit specimen, but they are connected by a form factor. Although the study was limited to a range of resistance in a single block shape and thickness, it could be established that it is possible to test half-unit units for quality control. This allows the other specimen half to be used for another test, simplifying the work controls in a smaller quantity of paving blocks needed and the possibility of using presses of lower capacity.
