ABSTRACT
ABSTRACT For a performance-based assessment of carbonation or chloride induced corrosion the models of the fib Model Code for Service Life (fib bulletin 34, 2006) are widely used. The relevant material parameters of these models are the inverse effective carbonation resistance and the coefficient of chloride migration which are determined by performance testing. The measurement of these coefficients is realized by means of the accelerated carbonation test (ACC-test) and the rapid chloride migration test (RCM test). Finally, the risk of carbonation or chloride induced corrosion can be calculated. But in reality, concrete structures are exposed in a combined manner. Therefore, a realistic performance-based durability assessment of concrete structures demands realistic performance testing methods. Against this background a new performance testing procedure will be presented that includes the fact of combined occurring exposure of carbonation and chloride ingress.
