Ground Granulated Blast Furnace Slag, Form : powder, Purity : 100%

Listing ID #1738670

Ground Granulated Blast Furnace Slag (GGBS or 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.
Application
GGBS is used to make durable concrete structures in combination with ordinary Portland cement and/or other pozzolanic materials. GGBS has been widely used in Europe, and increasingly in the United States and in Asia (particularly in Japan and Singapore) for its superiority in concrete durability, extending the lifespan of buildings from fifty years to a hundred years.
Two major uses of GGBS are in the production of quality-improved slag cement, namely Portland Blast furnace cement (PBFC) and high-slag blast-furnace cement (HSBFC), with GGBS content ranging typically from 30 to 70%; and in the production of ready-mixed or site-batched durable concrete.
Use of GGBS significantly reduces the risk of damages caused by alkali�silica reaction (ASR), provides higher resistance to chloride ingress � reducing the risk of reinforcement corrosion - and provides higher resistance to attacks by sulfate and other chemicals.
The use of GGBS in concrete results in following environmental benefits

• Saves energy
• Reduces emission of carbon dioxide
• Conserves natural resources.
