Manso, et al., 2004 3 carried out work in laboratory to produce concrete with good properties us-
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 ...
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 dried and ground in a rotating ball mill to form a fine powder, known as ground granulated blast furnace slag cement.
Blast Furnace Slag BFS cement is the combination of Ordinary Portland Cement OPC and fine Granulated Blast Furnace Slag GBFS gained as a byproduct in the steel making manufacturer with below 70 to that of cement.

The physical properties of Ground Granulated blast furnace slag GGBFS provides advantages to the concrete in fresh state as well as in its hardened state. It is always recommended for a concrete mix design, that would provide us with a denser mass of concrete, i.e. a solid that is free from voids. GGBS play an important role in making the ...
Jan 01, 2004 Using ground granulated blast-furnace slag GGBS under different alkaline conditions, we studied the mechanisms and extents of CrVI reduction and sorption and compared them to reactions with Portland cement PC. We also investigated the effects of mixing PCGGBS ratios on CrVI dissolution after carbonating the substrates.
Slag cement is often referred to as ground granulated blast-furnace slag GGBFS. As requested in 2001 by slag cement manufacturers and the Slag Cement Association, the American Concrete Institute officially reviewed and changed the terminology from GGBFS to slag cement ACI Committee 233, 2004.
Blast furnace slag is nonreactive in a high alkali environment, such as concrete and soils. Blast furnace slag concrete can be reliably pumped when the slag is supplied to the ready-mix production in a saturated condition. Use of the cementatious properties of ground granulated blast furnace GGBF slag was reported as early as 1774. GGBF slag has been used in concrete in
