VILA, P.; PEREYRA, M. N.  and  GUTIERREZ, Á.. Compressive strength in concrete paving blocks. Results leading to validate the test in half-unit specimens. Rev. ALCONPAT [online]. 2017, vol.7, n.3, pp.247-261. ISSN 2007-6835.  https://doi.org/10.21041/ra.v7i3.186.

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.

Keywords : quality control; concrete paving blocks; compressive strength; form factor.
