Assessment Of Historic Concrete Structures

Abstract
Concrete has been used as a construction material for several thousand years.
The concrete as known today was only developed around 150 years ago after the
technology was all but lost for a millennium after the fall of the Roman Empire.
Historic concrete structures therefore generally only date back second half of the
18th century. Structures that date further back are considered to be ancient
concrete. The structures that require attention and therefore an assessment
generally belong to the more recent period.
Concrete can be a very durable construction material and it was initially
thought that it could essentially last forever, however, this has subsequently been
proven to be wrong. Concrete can deteriorate as a result of structural
inadequacies and due to chemical interactions between the concrete constituents,
external aggressants and the embedded steel reinforcement. The deterioration
patterns vary from purely cosmetic cracking, cracks affecting the structural
integrity, ineffective protection against reinforcement corrosion and loss of steel
cross sectional area.
This paper provides an overview of many of the different types of
deterioration that can be encountered in historic concrete structures and how the
cause and severity can be assessed using different investigative techniques.
Keywords: concrete, corrosion, deterioration, assessment, investigation.
