Properties of Ferromin Old
Special Properties
The high density of FerroShield™ / FerroDense™ results in decreased volume for a given weight, or alternatively, an increased weight per given volume, offering a better overall economy.
The excellent particle characteristics of FerroShield™ / FerroDense™ enable the easy production of high quality, high strength concrete with a density of up to 240 lbs./ft3, some 65% denser than standard concrete which is typically 145 pounds per cubic foot.
FerroShield™ / FerroDense™ products have a long history of use as a construction material for both in-situ and precast applications. It is one of the few “environmentally friendly” materials available: it is a naturally occurring iron oxide which is harmless to the environment, and non-toxic in all its forms.
Concrete made with high density aggregates is favoured over other shielding technologies as it is also a structural material.
Advantages of high particle density in FerroShield™ and FerroDense™
- Reduced volumes = less excavation / transportation / reinforcement and time
- Increased weight for a given volume
- Reduced heat of hydration
- High submerged / saturated density
- High radiation shielding characteristics
- Space saving
- Noise and vibration dampening
- Thermal energy storage
