STEEL SLAG : THE HIGH PERFORMANCE INDUSTRIAL

Why is steel slag the proven industrial aggregate? There are two principal reasons. Firstly, there is a long success record in many countries, and secondly the material is environmentally friendly and will always be available wherever steel is made. It is only since the early 1900's that slag has been extensively re-cycled in a global sense.
