What is Ecocem (GGBS)

Ecocem GGBS is a high performance alternative to traditional cement that will increase the technical performance of your application, improve its appearance and minimize its environmental impact.

GGBS is an acronym for Ground Granulated Blastfurnace Slag, a by-product from the manufacture of Iron. Ecocem GGBS is used in combination with Portland cement to produce superior longer lasting concrete. A replacement rate of up to 70% is permitted by I.S EN 206-1.

Ecocem GGBS is an industrial by product that is diverted from landfill and up-cycled into a commodity product. On exiting the iron processing system, molten blastfurnace slag is rapidly quenched with water to form Granulated Blastfurnace Slag (GBS). Ecocem GGBS is then produced by drying and grinding the GBS at our milling plant in Dublin.

Ecocem GGBS improves performance in any situation, from housing to civil engineering applications across all industry sectors.
