The use of concrete,special purposes, such as protection from radiation, shielding densities of up to 4000 kg/m. can be achieved by using metallic iron or lead aggregates. Compressive strengths vary with the densities from approximately 0.48 N/mm. up to 69 N/mm. as do the thermal conductivities, from 0.11 to 2.6 W/m degC.
