GGBS For Concrete

GGBS for low carbon concrete production

Our portfolio of innovative, high-quality products includes Ground Granulated Blast Furnace Slag (GGBS), a cement addition providing an optimal mix of environmental benefits and performance.

A by-product of the iron industry, GGBS is made when blast furnace slag is finely ground into a powder. It possesses hydraulic properties, which means it can partially replace Portland cement in concrete mixtures. In fact, in the UK, GGBS can replace 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 furniture and concrete block paving.

Suitable for Buildings & Infrastructure Projects

Opting for GGBS can offer several key advantages:

  • Reduces the consumption of cement, resulting in lower carbon dioxide emissions and more sustainable construction products

  • It enhances the long-term strength, durability and workability of concrete when used as a partial cement replacement. 

  • When used in the correct proportions offers resistance to sulfate attack and chloride ingress, which can corrode steel reinforcement.

  • 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

  • Mitigates the alkali-silica reaction, which is a chemical reaction that can lead to concrete cracking and degradation.

  • Delivers an off-white finish, offering safety in darker areas and reduced lighting requirements while enhancing the overall aesthetics of your project.

  • As GGBS is a by-product, it's often more cost effective for concrete production
