Ground granulated blast furnace slag (GGBS) is a by-product from the blast-furnaces used to make iron. Blast-furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated at a temperature of about 1,500°C. When iron-ore, coke and limestone melt in the blast furnace, two products are produced—molten iron, and molten slag.

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 ...

Because of the poor grindability of slag, a high requirement is placed on the fineness of the product Therefore, the power consumption associated with grinding becomes the most important factor in the cost control of ground granulated blast furnace slag production and reflects the level of slag powder production technology,,

DIN standard was followed to get the maximum particle packing of aggregates and improved RAC performance. Again, to make RAC more sustainable, a mix design is also proposed to replace cement with widely used SCMs-coal fly ash (CFA) and ground granulated blast furnace slag (GGBS) at 30 and 50% replacement level, respectively.

2.2.3 Ground granulated blast-furnace slag GGBS is one of the by-products of iron and steel-making. It is economical in large quantities, so it is suitable for premixed concrete, bulk on-site concrete production, and precast product manufacturing ( Samad et al., 2017 ).

Additionally, the drying and grinding of GBFS produce ground granulated blast furnace slag (GGBFS), which is the basis of this review study. Due to rapid economic progress and massive demand for iron, a significant blast furnace slag is produced. Some of it is reused as a building material while the outstanding amount is disposed of the landfills.

Ground granulated blast furnace slag (GGBFS) shall comply with Specification 3102 and AASHTO M 302. Blended cements shall comply with Specification 3103 and AASHTO M 240.
