New methodology for the delimitation of areas to be repaired of a concrete affected by corrosion
Abstract
This paper describes the use on site of a portable X-ray fluorescence equipment (pFRX) for the quantification of chlorides in concrete samples taken from a structure affected by corrosion. Its application allows to delimit with more appropriate criteria the areas to be repaired by extending the intervention to areas adjacent to those clearly damaged, apparently healthy, but in which the concentration of chlorides in the concrete exceeds the threshold proposed by the EHE.
