David Tepke PE has Concrete Durability Repair Using Historical Clues published in ICRI January/February 2023 Concrete Repair Bulletin

The use of and development of concrete, and more specifically reinforced concrete, as a durable and versatile construction material has provided many opportunities for larger and more effective structures to serve the needs of society.  It has also brought the need for research, standardization, and new materials for advancement towards better, more efficient, and more sustainable structures.  Knowledge and provisions to address deterioration mechanisms such as freezing and thawing distress, corrosion, sulfate attack, and alkali-aggregate reactivity have evolved over time.  When evaluating older structures, it is important to understand the state of practice and requirements at the time of construction.  This article helps readers step into the shoes of the designers and constructors of older structures built throughout the 20th century and understand what was known at the time of construction.  This helps effectively understand what was known and what should be expected upon approaching an older building.  When were air-entraining admixture required for freezing and thawing resistance?  Were cast-in chloride contents limited?  Did the code address alkali-aggregate reactivity?  When did we know about sulfate attack?  These and other questions are answered in the article.
