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

Utilisation of iron ore tailings as aggregates in

Sep 07, 2015 The pH values for the various ages of the concrete ranges from 11.8 to 12.5. These values can be termed as having high alkaline conditions and will, therefore, make acid attack and potential for corrosion very low. This is a good sign of long-term durability of the iron ore tailings concrete.

Slag Wikipedia

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of
