Ultrafine GGBS (Ultrafine Ground Granulated Blast-Furnace Slag) is a finely ground supplementary cementitious material produced from granulated blast-furnace slag, a by-product of the iron and steel industry. Its ultrafine particle size and high specific surface area enhance reactivity and improve particle packing within the concrete matrix, contributing to greater density, strength and durability.
Used as a partial replacement for Portland cement, Ultrafine GGBS can help reduce cement consumption and associated carbon emissions while supporting high-performance concrete. It is particularly suited to high-strength, durable and sustainable concrete applications across modern construction.
Superior Performance. Less Cement. Greater Sustainability.
Our Ultrafine GGBS enhances the concrete matrix by filling micro-voids and promoting the formation of additional binding gel. The result is a denser, stronger and more durable concrete structure.
Supports strength development and long-term performance
Contributes to a denser matrix and improved resistance to deterioration
Supports smoother, more workable concrete mixes when properly proportioned
Improves resistance to aggressive chemical environments
Reduces the penetration of water and potentially harmful agents
Ultrafine GGBS brings more than performance benefits to concrete – it also delivers greater resource efficiency and a lower environmental impact. By reducing reliance on Portland cement and making productive use of an industrial by-product, Ultrafine GGBS supports more sustainable and responsible construction.
Enables partial replacement of Portland cement, helping optimise binder usage and reduce reliance on conventional cement.
Supports more sustainable concrete by reducing carbon emissions associated with cement production.
Makes productive use of an industrial by-product, supporting more efficient utilisation of resources and circular construction practices.
Helps balance performance and sustainability, enabling concrete solutions designed for the evolving demands of modern infrastructure.
It reacts with alumina compounds to block the formation of expansive ettringite, making it excellent for projects like water treatment plants.
It controls pore structures effectively, minimising drying cracks and enhancing overall structural integrity
Our Ultrafine GGBS is manufactured and tested in accordance with the requirements of IS 16715:2018 – Ultrafine Ground Granulated Blast-Furnace Slag – Specification, ensuring consistent quality and performance for demanding concrete applications.
