What is Superfine

Superfine is an additive for cementitious adhesives, mortars and grout based on Ground Granulated Blastfurnace Slag. It can also be used in Ultra High Performance Concrete (UHPC). Ecocem Superfine is an award winning Ecocem product.


Superfine is twice as fine as Ecocem GGBS with a D50 of 4µm and a Blaine value of 7000-8000 cm2/g. This makes it highly reactive at early ages and leads to high ultimate strength. As it is GGBS based it offers ultimate durability to chemical attack by chlorides, acids and sulphates.
