We exposed concrete specimens under salt attack
condition to estimate an amount of macrocell corrosion ,and measured half-cell
potential,amount of corrosion,crack width,amount of surface rising.As a result,it
becomes clear that the amounts of steel bar corrosion can be calculated by
measured half-cell potential values.Moreover,a crack width and an amount of
surface rising each other have a relationship with an amount of corrosion,so
it can be estimated by measured a crack width or an amount of surface rising. |
