Evaluacion de macroceldas de corrosion embebidos en vigas de concreto reforzado bajo ambiente salino
Abstract
El presente trabajo muestra los resultados de la evaluación electroquímica de vigas de concreto armado expuestas en solución de NaCl al 5% y en Agua Potable durante 18 meses. El concreto fue elaborado con relaciones aguacemento de 0.40 y 0.60. La evaluación se realizó empleando macroceldas de corrosión, potenciales a circuito abierto y ruido electroquímico. En los resultados se presentaron valores de mayor probabilidad de corrosión en los especímenes inmersos en salmuera con mayor relación agua-cemento, encontrándose el sistema pasivado. Las macroceldas fueron muy útiles como apoyo a la evaluación con técnicas electroquímicasDownloads
