Abstract

The present study investigates the possibility of re-surfacing previously corroded reinforcements and the suitability of the two electrochemical techniques that are widely used to determine the state of corrosion of steel (the corrosion potential Ecorr and the corrosion rate icorr). In order to test this, 32 pre-corroded B500SD reinforcing steel bars have been used for one year, where half of the bars have been cleaned to eliminate corrosion products. The other half have been maintained with the generated corrosion products. Subsequently, the bars have been embedded in cement mortar samples with variable amounts of chloride ion, and Ecorr and icorr have been measured for 250 days. The results showed that it is not possible to rework the reinforcement without removing corrosion products and that it is not possible to predict the passive or active state of steel by measuring Ecorr only.

    Project objectives

    El presente estudio persigue los siguientes objetivos: analizar la posibilidad de reacondicionar armaduras previamente corroídas; evaluar la idoneidad de las técnicas electroquímicas del potencial de corrosión (Ecorr) y la tasa de corrosión (icorr) para determinar el estado de corrosión del acero; determinar el efecto de la limpieza de productos de corrosión en barras de acero B500SD pre-corroidas tras un año de exposición; caracterizar el comportamiento electroquímico de barras embebidas en mortero con diferentes concentraciones de iones cloruro durante 250 días; y verificar la capacidad predictiva de Ecorr para distinguir entre estados pasivos y activos del acero.

    Most relevant results

    El estudio analiza la viabilidad de reutilizar armaduras previamente corroídas y evalúa la eficacia de dos técnicas electroquímicas para determinar la corrosión del acero. Los resultados más relevantes son: (1) se emplearon 32 barras de acero B500SD pre-corroidas durante un año, con la mitad limpiada y la otra mitad conservando productos de corrosión; (2) las barras se embebieron en mortero con cantidades variables de iones cloruro y se midieron Ecorr e icorr durante 250 días; (3) no es posible reacondicionar las armaduras sin eliminar los productos de corrosión; (4) la medición de Ecorr por sí sola no permite predecir el estado pasivo o activo del acero.
