GGBS For Concrete
Our portfolio of innovative, high-quality products includes Ground Granulated Blast furnace Slag (GGBS), a top-tier cement ingredient providing an optimal mix of environmental benefits and performance.
A by-product of the iron and steel industry, GGBS is obtained when blast furnace slag, a residue produced during the manufacturing of iron in a blast furnace, is finely ground into a powder. It’s usually finer than Portland cement and possesses hydraulic properties, which means it can partially replace Portland cement in concrete mixtures. In fact, in the UK, GGBS typically replaces 70% or more of Portland cement.
Applications for GGBS span a wide array of projects where sustainability and durability are paramount - from soil stabilisation and foundations to tunnelling street-style furniture and concrete block paving.
Opting for GGBS offers several key advantages:
Improved concrete properties
It enhances the long-term strength, durability and workability of concrete when used as a partial cement replacement.
Reduced environmental impact
By utilising a by-product like GGBS, the consumption of cement is reduced, resulting in lower carbon dioxide emissions and a more sustainable construction practice.
Reduced heat of hydration
GGBS has slower hydration properties compared to cement, which reduces the heat generated during the concrete setting process and minimises the risk of thermal cracking.
Reduced alkali-silica reaction
The use of GGBS can mitigate the alkali-silica reaction, which is a chemical reaction that can lead to concrete cracking and degradation.
Aesthetics
GGBS delivers a superior, near-white finish, offering safety in darker areas while enhancing the overall aesthetics of your project.
Lower cost
As GGBS is a by-product, its use can lead to cost savings in concrete production.
As a key addition in your concrete mix, GGBS can contribute significantly to performance while reducing environmental impact. Our customer service team is always on hand to provide technical assistance on how to use GGBS for your next construction project.
