This slag is later granulated by cooling it. For this, it is allowed to pass through a high-pressure water get. This result in quenching of the particles which results in granules of size lesser than 5mm in diameter. The main constituents of blast furnace slag are CaO, SiO2, Al2O3 and MgO. These are the minerals that are found in most of the cementitious substances. The particles are further

Fineness: Granulated blast furnace slag is a glassy granular material, and its particle distribution, shape, and grain size vary, depending on the chemical composition and method of production, from popcornlike friable particles to dense, sand-size grains. Pelletized blast furnace slag, in contrast to air-cooled and expanded blast furnace slag, has a relatively smooth texture and rounded shape

Granulated blast furnace slag (GBFS) is obtained by rapidly quenching the molten slag by using high-pressure water jets. It is glassy granular particles having generally smaller than 5 mm particle size like sand. The GBFS is often used after further processed by drying and then grinding to a very fine powder. GBFS can be used as a direct replacement for ordinary cement with varying replacement

The molten blast furnace slag is quenched almost immediately to form a material generally smaller than a #4 sieve. The efficiency, which the molten blast furnace slag is rapidly chilled, as well as the chemical composition of the slag source, largely determines its cementitious properties for use in concrete. After the granulated blast furnace slag is formed, it must be dewatered, dried and
