Ground Granulated Blast Furnace Slag Cement Factor

What is slag cement or ground granulated blast-furnace

What is slag cement or ground granulated blast-furnace

Granulated slag is the glassy, granular material formed when molten slag is rapidly chilled. Slag cement or GGBFS is granulated blast-furnace slag that has been finely ground and that is hydraulic cement. When slag cement is mixed with water, however, the initial hydration is much slower than portland cement mixed with water; therefore

L.F. Kahn, in Corrosion of Steel in Concrete Structures, 2016. Slag. Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the hydrated cement

Ground granulated blast furnace slag (GGBS)

Ground granulated blast furnace slag (GGBS) GGBS is primarily a binder used as an addition to cement which uses the latent hydraulic properties of GGBS to produce Portland blastfurnace cement (6-35% of GGBS) or blastfurnace cement (36-90% GGBS) produced by blending at the concrete mixer, or as a factory blend at the cement factory

Just like Portland cement, GGBFS must be finely ground before it can be used in concrete. If the GGBFS is ground by itself, it can be blended mechanically with cement at the cement mill to make ASTM C595, Type IS, Portland blast-furnace slag cement, or it can be added at the concrete plant to make slag concrete

Granulated Blast Furnace Slag - an overview

For the production of cement or cementitious materials, any type of blast-furnace slag can be used, but the most common is granulated or glassy slag due to its ease in handling and more rapid reactions between the glass and other raw materials [7]. As cement is hydrated, calcium silicate hydrates (C-S-H) and calcium hydroxide (C-H) form

What is slag cement

What is slag cement

Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy granules that yield
