GGBS Powder(Ground Granulated Blast furnace Slag POWDER)

The molter slag is a byproduct of an iron blast furnace, part of an integrated steel mill. And the Slag can be processed in two ways, resulting in two different products

1. Slag is deposited in pits and allowed to cool slowly by air.

air-cooled blast furnace slag aggregate

used in various construction applications (e.g., concrete, fill, base material, asphalt/hot

mix).

Air-cooled slag aggregate is non-reactive and is a relatively low-value product.

2. Slag is cool rapidly by water-injection.

granulator- glassy material with sand-like consistency.

Granulated slag, is then dried and ground to a fine powder, at which point it becomes

slag cement.

3. Slag cement

Slag cement is a hydraulic cement, which, like portland cement, chemically reacts with

water and forms the glue that causes concrete to become a solid, durable building

material.

Slag cement is a high-value product used primarily as a cement in concrete, and can

replace between 20 and 80 percent of portland cement in concrete (depending on

application and engineering requirements).

Among the measurable improvements are :

:Better concrete workability

: Easier finishability

: Higher compressive and flexural strengths

: Lower permeability

: Improved resistance to aggressive chemicals

: More consistent plastic and hardened properties

: Lighter color
