    Geotechnical And Environmental Impacts Of Steel Slag

    Dec 04, 2014 The expansion of free lime CaO and free periclase MgO, as well as the conversion of dicalciumsilicate C2S and the oxidation of iron and carbonation of CaO and Mg silicates results in the volumetric instability of steel slags Wang 2010. CaO lime can fully hydrate in a few days when immersed in water.

    Recycling And Environmental Issues Of Metallurgical Slags

    impact strength of the cooled slag5. Steel slags Steel slag is a by-product of the steelmaking from iron with a wide range of chemical and mineral compositions, resulted by different feeding material and smelting conditions. In comparison to BF slags, BOF and EAF slags are produced from an oxidation process, thus have higher iron oxides contents.

    Effects Of Ground Granulated Blast Furnace Slag In

    concrete design since the early 1900s Slag Cement Association, 2002. Slag cement is a byproduct of the iron-making process and is composed primarily of silica and calcium. In fine particle form, slag cement displays cementitious qualities similar to those of ordinary portland cement OPC. Slag cement can therefore be substituted for OPC in a

The experimental results confirm the assumption that the diffusion of magnesium oxide through the slag phase boundary layer controls the corrosion process. The corrosion mechanism seems to be the dissolution of elements in the refractory materials into the slag, followed by penetration
