FIELD: technological processes; measurement.
SUBSTANCE: method includes preparation of cement stone by means of its shredding. Cement stone immersion in corrosive solution is done in particles with size of 0.1 - 1.0 mm. Corrosive solution is selected from neutral or low alkaline medium in the form of sodium sulphide water solution. Cement stone soaking in corrosive solution is performed with continuous stirring with periodical sampling of liquid phase for chemical analysis for ion content. Determination of corrosion extent is done by change of sulphide-ions concentration. Method is characterised with reduction of corrosion detection time.
EFFECT: receipt of accelerated method for cement stone corrosion detection.
