ASTM C – 14 – Standard Specification for Aggregates for Radiation-Shielding Concrete
Work Item s – proposed revisions of this standard. It is informational only and not an official part of the standard; aastm full text of the standard itself must be referred to for its use and application.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Historical Version s – view previous versions of standard.
Also included are synthetic aggregates such as iron, steel, ferrophosphorus and boron frit or other boron compounds. Aggregates covered by specification include the natural mineral aggregates of either high density or high fixed water content, or both.
ASTM C637 – 14
This standard does not purport to address all of the safety concerns, if any, associated with its use. No other units of measurement are included in this standard.
Aggregates shall meet the required uniformity of specific gravity and fixed water content. This specification covers special aggregates for use in radiation-shielding concretes in which composition or high specific gravity, or both, are of prime consideration. Link to Active This link will always route to the current Active version of c37 standard.
These include aggregates that contain or consist predominately of materials such as barite, magnetite, hematite, ilmenite, and serpentine.
Coarse aggregate may consist of crushed ore, crushed stone, or synthetic products, or combinations or mixture thereof.
The materials shall also meet the required chemical composition for serpentine, limonite, goethite, barite, ilmenite, hematite, magnetite, iron, ferrophosphorus, boron frit, boron carbide, calcium carbide.
