Abstract:
There is a strong scientific rationale for
accelerating corrosion by using an equivalent current to achieve desired
corrosion ratios without compromising the formation of corrosion products.
Although the applied equivalent current technique has the advantage of
corroding the rebar embedded in the concrete at certain constant rates, the
corrosion ratio induced by the equivalent current cannot fully reflect the
actual corrosion ratio. Reasons why theoretical and actual corrosion mass
losses are not the same; it is attributed to various factors such as the resistance
of the concrete, the composition of the rebar, the electrical properties of the
minerals in the concrete. The aim of this research, to the knowledge of the
authors, is to establish an empirical relationship between the calculated
theoretical corrosion ratio and the actual corrosion ratio, using experimental
data created with previously recorded corrosion current density measurements of
24 reinforced concrete column specimens exposed to corrosion at different
concrete compressive levels. It is planned to compare the experimental findings
obtained using the empirical model to be developed with the results obtained
using a theoretical model reported in the literature. Thus, it is expected that
reinforcement corrosion can be evaluated more accurately by using equivalent
current values measured non-destructively.
