Steel slag. According to the American Society of Testing & Materials, blast furnace slag is a non-metallic compound containing calcium silicates and alum inosilicates and other game elements. It is produced in a blast furnace with iron in the form of melt. Also, according to the definition of this society, steel slag is a non-metallic compound.

Our calcium- and magnesium-based products and minerals are used throughout the iron- and steel-making process as binders or flux agents to form slag. Slag removes harmful impurities, such as silica, phosphorus and sulfur. Lhoist products also help improve productivity and enable you to comply more readily with environmental legislation.

Roads made from slag were first built in England in 1813 (although, in Roman times, metal slag was already used as a road-base material). As early as 1880, blast furnace slag and steel slag were used as a phosphatic fertilizer. By the 1880s, blocks cast of
