ASTM C – 14 Standard Specification for Aggregates for Radiation-Shielding Concrete
Aggregates shall meet the required uniformity of specific gravity and fixed water content. Aggregates covered by specification include the natural mineral aggregates of either high density or high fixed water content, or both.
This specification covers special aggregates for use in radiation-shielding concretes in which composition or high specific gravity, or both, are of prime consideration.
