1918, The NSA has promoted the use of Blast Furnace
and Steel Furnace Slag. Blast Furnace slag has been called
the "All-Purpose Aggregate" as it can be used
in all construction applications as either a normal weight
or lightweight (expanded or pelletized) aggregate depending
on how it was formed and processed. Blast Furnace Slag
is also quickly quenched by water or air to produce Granulated
Blast Furnace Slag. When ground to cement fineness, GGBS
(ground granulated blast slag) has been used extensively
as a Portland cement replacement in concrete. Steel Furnace
slag has been used in many construction applications and
as a raw ingredient in Portland cement manufacture, but
its primary use is as premium asphalt aggregate. These
types of slag and the uses are covered extensively in numerous
online documents and the applications
Slags are produced in many metallurgical
operations throughout the world and are considered a co-product
of the production of iron and steel. Slag is an environmentally
sound material that has been used to aid in the remediation
of many environmentally damaged areas such as Acid Mine Discharge.
