Blast furnace slag is a calcium-silicate-based product removed from the top of molten iron during its extraction from ore in a blast furnace.
Ground granulated blast-furnace slag, GGBFS, is a by-product of iron in blast-furnace. It mainly consists of silicate and aluminosilicate of melted calcium that periodically needed to be removed from the blast furnace.
GGBS is one of the by-products of iron and steel-making. It is economical in large quantities, so it is suitable for premixed concrete, bulk on-site concrete production, and precast product manufacturing(Samad et al., 2017).
In Iranian Iron & Steel plants, Slags are generated at three different stages of processing; Basic Oxygen Furnace (BOF), Electrical Arc Furnace (EAF), and Granulated Blast Furnace (GBF).
At Romak Trading co., we supply high-quality GGBFS & GBFS for diverse ports of export.
