GGBS reduces the carbon footprint of concrete production, as it requires less energy to produce than OPC cement. This makes it an environmentally friendly alternative to OPC cement.
GGBS (Ground Granulated Blast-furnace Slag)
What is GGBS?
Ground Granulated Blast Furnace Slag (GGBS) is a by-product of the iron and steel industry. It is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
Advantages of GGBS in Concrete
GGBS has several advantages over OPC cement. It improves the durability of concrete, reduces the heat of hydration, and reduces the risk of alkali-silica reaction. It also reduces the carbon footprint of concrete production, as it requires less energy to produce than OPC cement
Using GGBS as a partial replacement of OPC cement in concrete production has several benefits. It improves the workability of concrete and reduces the amount of water required for mixing. It also reduces the permeability of concrete and increases its resistance to chemical attack.
Calcium silicate hydrates (C-S-H) are formed when GGBS is mixed with water and OPC cement. These hydrates are responsible for the strength and durability of concrete.
Sustainability
Durability
GGBS improves the durability of concrete by reducing the risk of alkali-silica reaction and increasing its resistance to chemical attack. This makes it ideal for use in harsh environments where concrete is exposed to chemicals or other corrosive substances.
