Accelerated evaluation of corrosion inhibition by means of the integral corrosion test

The cement can be of any class depending of the particular application of the results although in present case an Ordinary Portland Cement was used.

Two types of concrete were fabricated with a characteristic strength of 50 MPa. For the exercise sodium known corrosion inhibitor was added to the mix in proportions, as indicated by the inhibitor manufacturer, of 0, 1.5, 2 y 2.5% of NO2− by cement weight.
