|"I just googled 'concrete cancer' and got some hits; check this out:
'Concrete Cancer, often identified by flaking concrete (concrete spalling) or rust stains which originate deep within the concrete is a serious problem. Often people mistake the signs for weathering caused by the elements, but whilst this may have a part in exacerbating the problem, the real problem lies within the concrete itself.
Concrete cancer is caused by rusted reinforcing from within the steel. As steel rusts it can expand up to 7 times its original size causing the surrounding concrete to be displaced. As the steel pushes the concrete away, more water gets to the steel expediting the process.'
