Original Abstract

A simple method for determining the corrosion dependence of steel reinforcement on the content of chloride and hydroxide ions is described. Steel test specimens were immersed for nine months in solutions with 0.03%, 0.3% and 3% NaCl with increasing concentrations of hydroxide ions, and pH of 8.5 to 13. The test specimens were cleaned of corrosion products and weighed at given time intervals of one month. The dependence of mass loss expressed as a percentage of the concentration of chloride and hydroxide ions was determined. The concentration threshold of the cCl-/cOH- ratio of 0.5 was evaluated from the results. Higher values of this ratio resulted in the formation of corrosion products on the surface of the test specimens.
