Milled and blended to produce more environmental, high-performing cement products

Blast furnace slag is naturally cementitious and is commonly used in the cement industry to blend with other materials. Steel slag, from the converter furnace, is also suited for use in cement manufacturing. Once milled to a fine material, it is absorbed into the mix in the kiln. Cement made with slag aggregate can achieve permeabilities and strengths that compare favourably to concrete made with conventional aggregates.

In addition, Slag used in the manufacturing of Portland cement can reduce environmental CO2 and NOx emissions, delivering a more environmentally friendly cement product.
