This paper describes a corrosion study performed on an ice rink. The purpose of the study was to evaluate the extent and increase in corrosion of low carbon steel refrigeration tubes and the reinforcing steel embedded in a concrete slab-on-grade. A copper-copper sulfate half cell was used in the assessment. Chemical analyses, microscopic examinations and destructive examinations were used to supplement and confirm the results of the half cell testing.
An increase in corrosion activity was determined by comparing the results of half cell surveys conducted in 1989 and 1990. The cause of the corrosion activity was determined from chemical analyses, microscopic examinations and destructive techniques.
