   These products are made from steel slag, which
occurs as a by-product during steelmaking. Due to their unique
characteristics, they are used in various fields. With awareness of
the need for environmental protection increasing, these steel slag
products are highlighted as excellent materials from the viewpoint
of resource and energy conservation.
Â
   Steel slag is used as raw material for blast
furnace cement. Compared to mixed cement, blast-furnace cement
offers the great advantages of increased durability (high
resistance to seawater, reduction in alkali-aggregate reactivity,
etc.) and enhanced long-term strength, along with lower CO2
off-gassing.
Â
Applications & Benefits:
It is a type of eco-friendly green building material, has been
recognized as one of the best Secondary Cementitious Material for
building high durable concrete structure in the world
today.Â
1 Durability
GBFS has now effectively replaced sulfate-resisting Portland cement
(SRPC) on the market for sulfate resistance because of its superior
performance and greatly reduced cost compared to SRPC. Most
projects in Dublin's Docklands, including Spencer Dock, are using
GBFS in subsurface concrete for sulfate resistance.
Â
2 Appearance
In contrast to the stony grey of concrete made with Portland
cement, the near-white color of  GBFS cement permits
architects to achieve a lighter colour for exposed fair-faced
concrete finishes, at no extra cost. GBFS cement also produces a
smoother, more defect free surface, due to the fineness of the GBFS
particles. Dirt does not adhere to  GBFS concrete as easily as
concrete made with Portland cement, reducing maintenance costs.
 GBFS cement prevents the occurrence of efflorescence, the
staining of concrete surfaces by calcium carbonate
deposits.Â
3 Strength
Concrete containing GBFS cement has a higher ultimate strength than
concrete made with Portland cement. It has a higher proportion of
the strength-enhancing calcium silicate hydrates (CSH) than
concrete made with Portland cement only, and a reduced content of
free lime, which does not contribute to concrete strength. Concrete
made with GBFS continues to gain strength over time, and has been
shown to double its **-day strength over periods of *0 to *2
years.
4 Sustainability
Since GBFS is a by-product of steel manufacturing process, its use
in concrete is recognized by LEED etc. as improving the
sustainability of the project and will therefore add points towards
LEED certification. In this respect, GBFS can also be used for
superstructure in addition to the cases where the concrete is in
contact with chlorides and sulfates. This is provided that the
slower setting time for casting of the superstructure is
justified.
Â
5 High-performance concrete additive, especially suitable for:
Preparation of the harbor and marine concrete structures with
highÂ
resistance to corrosion by chloride ion.
Preparation of corrosion-resistant concrete, improving durability
ofÂ
concrete structure in soleplate salt and alkali regions.
Preparation of concrete which provides effective prevention
measures for theÂ
potential active alkali-aggregate reactions in concrete.
Preparation of low heat concrete which, effectively reducing the
risk ofÂ
temperature cracks in early period of the mass concrete
structure.
Preparation of pumping concrete to effectively reduce the slump
loss in theÂ
construction in summer, hence improving the workability of
concrete.
Preparation of self-compacting concrete to have effective control
onÂ
bleeding and segregation of high fluidity concrete.
Â
6 Super-reactive cementitious additives, especially suitable
for:
· Production of medium content (****0%) slag cement,
improvingÂ
the strength of all ages.
· Production of low heat cement with highÂ
GBFS substitutions (****0%), used for mass or port/marine
concreteÂ
structures.
