Ferromin’s high density aggregates answer the call when a design requires specific grades of low-volume high-weight concrete or loose ballast. Our high quality aggregates have been used successfully in Cancer Treatment Buildings, Medical Research Reactors, Nuclear Reactors and Spent Fuel Canister production.

Ferromin’s Dense-AGG is a high grade, high density aggregate manufactured from the natural iron oxide, magnetite. Ferromin’s reliable supply of magnetite, and their ability to also process ilmenite and specular hematite, allow us to offer proprietary formulations of fine aggregates in a range of densities, while maintaining concrete gradation specifications.

Dense-AGG is available as standard grades or tailor made to unique and precise specifications. It can be used as
loose ballast, or as aggregate to produce high-quality, high-density concrete which is easily produced and placed using standard equipment.
