.... A more refined steel cathodic polarization characterization was introduced and demonstrated by accounting for the effect of electrode potential, as an added term to the nominal activation energy of the cathodic reaction. temperature concrete corrosion resistivity activation energy INTRODUCTION...

... SCC is about 2 to 3 times higher than transgranular SCC. Also, by studying the effect of temperature on the crack propagation rate the activation energy in both modes of cracking was found to be similar thereby suggesting that the rate limiting step in both types of cracking may be the same...
