 RAD
BAN™ is a heavy aggregate designed for radiation shielding concrete
and all other heavy aggregate applications.
RAD BAN™ meets the requirements of ASTM Specification
C-33-86 (Standard Specifications for Concrete Aggregates) and ASTM Specification
C-637-84 (Aggregates for Radiation Shielding). Principle uses include hospital
construction or renovation, radiation therapy suites, university nuclear
research facilities, commercial nuclear power plants, nuclear waste containment
sites, military nuclear refueling facilities, counterweights for bridge
construction, off-shore pipeline stabilizer and heavy aggregate.
