Iron-Ore Concrete in Radiation Protection
Iron-ore concrete was introduced as a radiation protection material by SIE- VERT (4) as early as 1933. It was intended at that time for protection barriers against radium gamma radiation. The employment of the readily available high grade Swedish iron ore as an aggregate produced a concrete the density of which was 3.7 g/cm3; its strength was found to be about the same as that of ordinary ...
