Ground Granulated Blast
Furnace Slag (GGBFS)

Product Overview
GGBFS
Product Type:
Supplementary Cementitious Material (SCM)
Description:
GGBFS is a fine granular material that is a byproduct of the iron manufacturing process. It is produced by quenching molten blast furnace slag with water or steam, resulting in a glassy granular product. GGBFS is known for its pozzolanic properties, which make it an excellent choice for enhancing the properties of concrete and other construction materials.

Key Features
Enhance Strength, Durability, and Sustainability with every mix
Pozzolanic Reactivity
GGBFS is highly pozzolanic and reacts with calcium hydroxide to produce additional cementitious compounds, enhancing the strength and durability of concrete.
Enhanced Durability
It improves concrete's resistance to sulfate attacks, chloride penetration, and alkali-silica reactivity (ASR).
Reduced Heat of Hydration
It helps in controlling the heat generated during the cement hydration process, making it suitable for mass concrete applications.
Environmental Benefits
Using GGBFS in concrete significantly reduces carbon emissions and conserves natural resources, making it an environmentally responsible choice for construction projects.
Improved Workability
GGBFS enhances the workability of concrete, making it easier to place and finish.
Versatile Applications

Concrete Production
GGBFS is widely used as a supplementary cementitious material in concrete production, reducing the need for Portland cement and improving the long-term performance of concrete.
Sustainable Construction
It is a key component in sustainable construction practices, helping reduce the environmental impact of construction materials.
Mass Concrete
It is suitable for mass concrete applications, such as dams, bridges, and foundations, where heat generation during curing needs to be controlled.
Infrastructure Projects
GGBFS is valuable in infrastructure projects, including roads, bridges, and tunnels, where durability and long-term performance are crucial.
High-Performance Concrete
GGBFS is used to produce high-performance concrete with enhanced strength and durability
