Ash Utilisation an Australian Perspective Fly Ash

Bottom ash and boiler slag comprise approx 10 to 15% of the total CCP's produced and range in grain size from fine sand to coarse lumps. They have chemical compositions similar to fly ash, but may contain greater quantities of carbon and are relatively inert because they are coarser and more highly fused than fly ash.
