A method for determining the passivating properties of a mixture containing cement and water. Taking three elements that are referred to as first-third electrodes. Fixing at least one electrode on a support such that the electrodes are electrically insulated reciprocally and the mixture is able to come in contact with a face on each electrode. Applying between the first and third electrodes a direct current, referred to as first direct current, of predetermined intensity value and predetermined polarity, resulting in electrolytic reactions on the third electrode for a first duration, and then measuring voltage between the second and third electrodes. Storing the measurement for the variation of said voltage, comparing the variations in the voltage with predetermined data defining at least whether or not a mixture has passivating properties, and determining at least whether or not the mixture has such passivating properties. |
