How does concrete cancer occur?

Three key ingredients cause concrete cancer – Iron, Water and Oxygen, and the process starts when:

  • Moisture hits the internal steel iron, and combines with the carbon dioxide in the air, forming weak carbonic acid.
  • As this acid forms, it causes the iron to dissolve, allowing water to start breaking down its components – hydrogen and oxygen.
  • This then forms an oxygen and iron bond freeing electrons, creating what is commonly known as rust.

Hi-rise apartment buildings built back in the 1970s have been the hot topic of discussion, as the effects of concrete cancer are starting to show, some with disastrous outcomes.

This issue led to Brisbane’s City Hall being closed for two years over 2012 and 2013. The Brisbane City Council spent over $215 million to preserve the heritage listed dwelling.
