The American Concrete Institute (ACI) provides guides, specifications, and code documents related to concrete durability. The authors reviewed two code documents from ACI Committees 318 and 350, two guidance documents from ACI Committees 201 and 222, and a specification document from ACI Committee 350, and observed that several discrepancies exist in terms of providing uniform durability requirements for freezing and thawing and chemical sulfate attack of concrete, and allowable chloride limits for new construction. By analyzing existing concrete durability data from published literature, laboratory testing, and field exposure sites, recommendations on unified durability requirements and exposure class descriptions are made for potential adoption by ACI Committees 201, 222, 318, and 350. Keywords: ACI committees; chemical sulfate attack; chloride limits for new construction; freezing and thawing; unified durability guidance.
INTRODUCTION Insufficient durability design of concrete structures and improper execution can result in their failure. Therefore, it is crucial for durability codes and specifications to specify concrete durability requirements clearly. [...]
