Corrosion Basics and Assessment Techniques for Historic Concrete and Masonry Structures
Description
Corrosion is a universal condition affecting existing reinforced concrete and historic masonry clad steel frame construction. Corrosion can be understood as a series of chemical changes which occur within the structure, accelerated by a number of influencing factors. Due to the symbiotic relationship of the materials, deficiencies in concrete or cladding, lead to propagation of steel corrosion. As the steel corrosion initiate, it damages the concrete or masonry cladding, further exasperating conditions and posing a risk to the longevity of the structure, to pedestrians, and without mitigation, will lead to cyclic deterioration and ever costly repetitive repairs. As corrosion is a measurable and quantifiable reaction, there are key non-destructive test methods which can be utilized to determine risk, rate, and severity of corrosion on an existing structure which is further complemented with service life models that can provide the client with time frames for interventions. The seminar will cover corrosion basics, deterioration, diagnostics, and touch on long-term durable repairs which proactively address corrosion in existing and historic structures.
