STRUCTURE magazine Durability of Reinforced Concrete

Historically, reinforced concrete has been thought of as very forgiving when it comes to the amount of time the material performs in service. Although there is a lot of truth to this, the environment inevitably can shorten reinforced concrete’s life expectancy, resulting in costly repairs and disruption to everyday life.
