It can smelt ore at twice the speed of a furnace, but it will use up fuel twice as fast, and it can only smeltore-related blocks. Granulated Blast-furnace Slag, consisting essentially of silicates and alumino-silicates of calcium and other bases, is formed when molten iron blast-furnace slag is rapidly chilled (quenched) by immersion in water. Blast furnace slag (BFS) A technical report on the manufacturing of blast furnace slag and material status in the UK. Thus, the structures exposed to chloride benefit from the improved strength and longer useful lifetime. Blast furnace slag is defined as “the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten condition simultaneously with iron in a blast furnace.” [1] In the production of iron, blast furnaces are loaded with iron ore, fluxing agents, and coke. SAFETY DATA SHEET C.T.V. Blast-furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated at a temperature of about 1,500°C. BLAST FURNACE SLAG .

Of these two products, the most commonly used is Portland Blast Furnace Cement (PBFC), which contains approximately 30% of blast furnace slag. Ground granulated blast furnace slag is an environmentally friendly product. Ground Granulated Blast Furnace Slag (GGBFS) is a by product of the steel industry. When GGBFS is mixed with water, initial hydration is much slower as compared with Portland cement. In simple words, ground granulated blast furnace slag is a waste product in the manufacture of pig iron. Introduction 3 2. BF slag is sometimes erroneously classified, and often looked upon, as industrial waste material. Slag is a by-product from steel plants, which is obtained from blast furnaces, during the separation of iron from iron ore. Ground granulated blast furnace slag consists of silicates and aluminates of calcium and other bases. Ground Granu-lated Blast-Furnace Slag (GGBFS) is a glassy granu-lar material formed when molten blast-furnace slag is rapidlycooled,usuallybyimmersioninwater,andthen groundtoimproveitsreactivity.Themajorcomponents of blast-furnace slag are SiO2, CaO, MgO, and Al2O3, which are common components in commercial silicate glasses. The Crude Blast Furnace (formerly named Blast Furnace) is a multiblock structure added by Immersive Engineering.
