01/07/2016  Early 20th-century engineers thought reinforced concrete structures would last a very long time – perhaps 1,000 years. In reality, their life span is more like 50-100 years, and sometimes less. Building codes and policies generally require buildings to survive for several decades, but deterioration can begin in as little as 10 years.

The idea of overcoming corrosion problems by using higher strength or more dense concrete with lower permeability has been shown to be counter-productive and to have worsened the problem. The root cause of chloride induced concrete corrosion is the fact that all normal concrete is very absorptive and the speed of absorption is rapid. Under conditions of wetting and drying it relentlessly sucks ...
