摘要

To extract copper, mines insert copper anodes into an electrolyte solution that is extremely acidic, with a pH of less than Stored in electrolytic cells as a blue fluid, the acidic solution creates significant loads. These loads are supported by a series of columns in the basement below the cell house. They serve as secondary containment for the electrolyte. Over the years, these support columns degrade and become susceptible to structural failure as the electrolyte leaks through the ceiling and into the column-to-beam connections. Exposure to electrolytes in the basement of the cell house causes the steel reinforcement within the concrete columns to corrode. Corrosion leads to oxidation in the columns. This creates an internal pressure that cracks the concrete. Corrosion of the reinforcing steel and delamination of the concrete shell causes structural degradation and failure of the columns.
