Slag SMŠ 400
Granulated blast furnace slag, very finely ground SMŠ 400
Very finely ground blast furnace granulated slag is a powdered latent hydraulic binder produced by grinding of dried blast furnace granulated slag to the required parameters.
Area Of Use
Finely ground blast-furnace slag is particularly suitable as a hydraulic component in concrete mixes to increase strength and resistance to aggressive environments. Slag can also be used in mortar mixes or with other materials to produce hydraulic binders for soil stabilisation.
