Work Item
ASTM WK95526
Revision of C638-20 Standard Descriptive Nomenclature of Constituents of Aggregates for Radiation-Shielding Concrete
Rationale
The subcommittee C09.20 has been made aware of multiple product categories that reference or specify C638 (and C637) for products other than radiation-shielding concrete. To better reflect the industry use of this standard, the title is being balloted to replace “radiation-shielding concrete” with the term “high-density concrete” and expanding the scope to include other applications outside of radiation-shielding concrete.
