ASTM International’s concrete and concrete aggregates committee (C09) is developing a proposed standard that will help experts examine examples of deteriorated hardened concrete. The proposed guide (WK96177) will offer a standardized approach for assessing internal swelling reactions in concrete using the Data Rating Index (DRI).
“The proposed standard will provide a clear and repeatable way to measure the extent of damage, which is essential for determining whether rehabilitation is needed or if a structure remains safe,” says ASTM member Leandro Sanchez.
According to Sanchez, the proposed standard will be valuable for laboratories, infrastructure owners, consultants, and regulatory bodies involved in durability assessments and forensic investigations of concrete structures. Manufacturers and researchers may also benefit from the consistent methodology when evaluating materials or validating migration strategies.
“This guide builds on years of research and field application of the DRI method, which has proven effective in identifying damage due to internal swelling reactions such as alkali-silica reaction (ASR) and delayed ettringite formation (DEF),” says Sanchez. “The task group includes experts from academia, industry, and government agencies, and we’re committed to ensuring the proposed guide is both scientifically rigorous and practically applicable.”
Sanchez invites all interested parties to join in the development of WK912177.
“By enhancing the assessment of concrete durability, the proposed standard will contribute to safer, longer-lasting infrastructure and more efficient use of resources,” says Sanchez.
ASTM welcomes participation in the development of its standards. JOIN ASTM.
