ABSTRACT
The corrosion state of the reinforcement in concrete containing various proportions of fly ash was analyzed within specified limits of corrosion current density https://www.w3.org/1998/Math/MathML"> 0.5 - 1.0 μ A / c m 2 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429227196/8b5c0a5d-ddea-4c88-8eea-7152f7afb008/content/eq10517.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> . The reinforced concrete specimens were subjected to https://www.w3.org/1998/Math/MathML"> 10 % N a C l https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429227196/8b5c0a5d-ddea-4c88-8eea-7152f7afb008/content/eq10518.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> solution to de-passivate the reinforcement bars. Activation polarization was found to be the governing mechanism of rebar corrosion irrespective of the fly ash addition. It was perceived that the longer curing for fly ash concrete has delayed the onset of the corrosion of rebars but on the other hand it has increased the probability of pitting corrosion.
