    Revision of C637 - 09 Standard Specification for Aggregates for Radiation-Shielding Concrete

    (What is a Work Item?)

    Active Standard: C637 - 14

    Developed by Subcommittee: C09.41 | Committee C09 | Contact Staff Manager


    1. Rationale

    Rationale for Ballot: The Blue Book Manual for Form and Style of ASTM Standards (Mar 2013 edition) states in Section A7 Terminology: A7.1 Every standard should include a section on terminology. A7.1.1 All significant terms that may have a meaning more specialized or more restricted than the common dictionary meaning should be defined within a standard, or the terminology standard should be referenced. Therefore, the purpose of this ballot item is to add a section on terminology as required by ASTM. Renumber sections as required. Only the items marked are being balloted at this time.


    aggregates; boron frit; calcium boride; high-density aggregates; high water-content aggregates; hydrous aggregates; radiation shielding concrete
    ; Aggregate (radiation-shielding concrete); Boron-containing minerals; Boron frits; Concrete construction materials/applications--specifications; Density--concrete; Fixed water content; Loss on ignition (LOI); Radiation-shielding concrete; Specific gravity--aggregates;
