Steel slag is a by-product formed during the manufacture of steel. It has a complex chemical structure comprising of oxides and silicates formed by the oxidation of impurities within the steel. The steel slag contains a proportion of uncombined (free) lime and magnesia which expands in the presence of moisture but when handled correctly this material can be converted into a high quality road construction aggregate. Steel slag aggregate is accepted in many standards internationally for the production of both unbound and coated road construction materials. Due to its excellent physical and mechanical properties it is actually specified in some circumstances for the production of surfacing materials which exhibit superior performance (strength, durability, skid resistance) characteristics to those of existing natural aggregates. By utilising steel slag in this way the construction industry benefit from a high specification aggregate and the environment benefits from reducing landfill and the conservation of natural resources.
