Blast Furnace Slag Aggregate Cement To Manufacture Concrete

Granulated blast furnace slag (GGBS) Primarily used in the manufacture of concrete products as a cement replacement. It has been used in cement combinations and as a cementitous component in concrete for many years and the use of GGBS will continue to help meet sustainability demands.

GGBS cement can be added to concrete in the concrete manufacturer's batching plant, along with Portland cement, aggregates and water. The normal ratios of aggregates and water to cementitious material in the mix remain unchanged. GGBS is used as a direct replacement for Portland cement, on a one-to-one basis by weight. Replacement levels for GGBS vary from 30% to up to 85%. Typically 40 to 50% is used in most instances.

18.10.17 Blast furnace slag Blast furnace slag is used successfully as a mud-to-cement conversion technology in oil well cementing worldwide because of economic, technical, and environmental advantages [86 ]. Slag-mix slurries were used as primary, temporary abandonment and sidetrack plug cements during prospect predrilling in the Gulf of Mexico.

The bulk density of pelletized blast furnace slag is typically 850 kg/m 3 (55 lb cf). Appropriate production control ensures the formation of crystalline material, which is preferable for use as aggregate; this is in contrast to blast furnace slag pellets used in the manufacture of blast furnace cement (Neville, 2012).

Iron and steelmaking slag has been employed in the European Union (EU) as a component of both cement and concrete.
