Electrochemical study of the inhibition effect of cow bone ash on the corrosion resistance of mild steel in artificial concrete pore solution

Substitution of cement powder with sustainable waste products is the focus of research in concrete technology. Cow bone ash (CBA) was studied to determine its inhibition effect on Mild Steel corrosion in artificial concrete pore solution by potentiodynamic polarization technique (between potentials...
