Steel Slag - an overview | ScienceDirect Topics

Aluminum oxide (Al 2 O 3) content in steel slag exists in solid solution. In OPC clinker, Al 2 O 3 forms calcium aluminate and calcium aluminoferrite. (iii) The total amount of iron oxide in steel slag exists in the form of FeO and Fe 2 O 3, but mainly in the form of bivalent FeO. Normally, FeO accounts for about 70% of total iron content.

Granulated blast furnace slag is formed in the blast furnace from flux, coke ash, and iron-bearing materials. The rapid cooling of a liquid substance with water or air forms a fine-grained bulk material in the form of vitreous or crystalline granules with an average size of 2–8 mm. Slag density, depending on the composition, is 2.8–3 g/cm 3 .

11 Benefits of Concrete House Construction | Fox Blocks

Unlike concrete blocks, ICF provides high thermal resistance. Concrete blocks alone provide little thermal resistance. For example, an eight-inch thick block has a thermal resistance value of only between R-1.9 and R-2.5. Therefore, concrete block construction requires a builder to apply insulation to achieve sufficient thermal resistance.
