Concrete Deterioration

Matthew Stuart, PE, SE

Reinforced concrete is a very versatile and durable building material. Reinforced concrete efficiently combines the best properties of concrete and reinforcing steel into a strong structural element. In addition, the high alkalinity of concrete helps to protect the embedded steel from corrosion. However, due to the porosity of concrete, its use in exterior environments and tendency to be exposed to deleterious chemicals, this material can easily be subjected to deterioration.

Deterioration of concrete can take the form of corrosion of the internal reinforcing or degradation of the exposed surface of the material. Cracks increase the likely hood of the deterioration of concrete in most environments. Concrete can also become deteriorated via freeze/thaw cycles, internal aggregate reactions and heat. Visual and destructive methods of investigation should be employed when determining the cause of concrete deterioration. The results of the physical observations and material tests associated with a proper investigation should be used to establish the best methods of repair and prevention of further deterioration.

This course includes a true-false quiz at the end, which is designed to enhance the understanding of the course materials.
