Abstract
The effect of 5% Rice Husk Ash (RHA) as a mineral admixture on the
corrosion behavior of reinforced steel in presence of different concentrations
of chemical admixtures as lignosulphonate and superplacticizer has
been studied, in HCl, H2SO4 acid media using Impressed CurrentMethod,
Impressed VoltageMethod and Potentiostatic PolarizationMethod. It was
found that, the samples which contain 5 % RHA in presence of chemical
admixtures are more resistant to the corrosive media than that containing
chemical admixtures only. This is due to the large surface area of RHA
which decrease the permeability of the samples.
