Granulated blast furnace slag is a glassy granular material that varies, depending on the stone composition and method of production, from a coarse, popcornlike friable structure greater than 4.75 mm (No. 4 sieve) in diameter to dense, sand-size grains passing a 4.75 mm (No. 4) sieve. Grinding reduces the particle size to cement fineness
SLAG IRON AND STEEL THM : Tonne Hot Metal Blast Furnace Slag In the blast furnace, the slag floating over molten pig iron (hot metal) is flushed out in slag pot and then sent to slag granulating plant or to cooling pits. Depending upon the cooling process, three types of slags are generated, namely, air-cooled slag, granulated slag and
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with
Investigations have been carried out into the development of bricks from granulated blast furnace slag, a byproduct of the iron and steel industry. The study reveals that good quality bricks can be produced from a slag-lime mixture and sand by pressing the mix at a pressure of 50 kg/cm 2.

Expanded blast furnace slag is a small part of the supply of structural lightweight aggregates. Annual production since 1985 has been about 1 million short tons (9×10 5 t); in 1997 that was about 12% of the total lightweight aggregate construction-related usage. The amount used was only 0·6% of all blast furnace slag produced, and the supply
