High density (heavyweight) concrete

High density (heavyweight) concrete is used for radiation protection from X-ray, gamma, neutron and electron radiation. Its application in construction is mainly for the prevention of radioactive effects. The degrees of protection from these are determined by the thickness of the elements and the volume mass of the material.

In order to obtain as much mass of concrete as possible, high density materials such as barite, magnetite, limonite, and metal fillers are used as aggregates. The high density (heavyweight) concrete has a weight of 2600 – 3300 kg/m³.

Application

• Radioactive protection in zones and medical institutions (oncology clinics)
• Ballast weights for cranes, ships and others.
• Safes
