GROUND GRANULATED BLAST FURNACE SLAG
Product Code : 25
Brand Name : STALLION ENERGY
Product Description

GROUND-GRANULATED BLAST-FURNACE SLAG (GGBFS)

Ground-granulated blast-furnace slag (GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. It is suitable for applications in marine environment, mass concreting and sulphate environment, water retaining structures, basement and other structures which require low heat of hydration.

 

GGBFS is off-white in colour and substantially lighter than Portland cement. The whitish colour is also observed in concrete made with GGBS, especially at addition of 50% and above. The more pleasing appearance of GGBFS concrete can help soften the visual impact of large structure such as bridges, retaining walls, etc.

 

Advantages and Benefits of specifying GGBS are outlined below:

 

Superior Quality Concrete

o    Improved workability, pump-ability and compaction characteristics for concrete placement

o    Increased strength

o    Reduced permeability

o    More chemically stable

o    High resistance to chloride penetration

o    High resistance to sulphate attack

o    High resistance to ASR ( Alkali Silica Factor)

o    Very low heat of hydration

o    Improved resistance to attack from fire

 

 

    Low Environmental Impact

o    Production of GGBS involves virtually zero CO2 emissions

o    Use of GGBS extends the life cycle of concrete structures

o    Enhanced durability, reduced maintenance and repair costs

o    Reduces lifetime construction costs

 

 

Superior Appearance

o    Improved surface finish

o    Lighter and more even colour

o    Enhanced reflectivity for greater visibility and safety

o    Suppresses/eliminates efflorescence

 

 

Better Value for Money

o    Enhanced durability and strength—longer life

o    Enhanced architectural appearance—reduced need for other expensive finishes or painting

o    Enhanced environmental performance—reduce the risk of attracting carbon taxes

o    Lower maintenance costs

o    Enhanced life cycle

o    No additional premium on material costs

o    Overall better value for money
