Bottom Ash Bottom ash can be used as a replacement for aggregate and, as it is lighter than conventional aggregate, it is useful in lightweight concrete applications. Bottom ash is free-draining and is well-suited for use in base course and shoulder mixtures, or cold mix applications. Evonik Power Minerals markets bottom ash as steasint®. We supply bottom ash under the brand name steasint®. Due to the porous structure of the individual grains, steasint® bottom ash has material properties similar to those of natural and other artificial lightweight aggregates. All bottom ashes marketed by Evonik Power Minerals are regularly monitored to ensure consistently high quality. In addition, some grades of bottom ash are certified as lightweight aggregates fior use in concrete, mortars and injection mortars. Their quality is controlled according to EN 13055-1:2002 and they meet the criteria for CE Marking. Currently, steasint® is used mainly in its unbound form in earthworks and road construction, and as a high quality constituent in the manufacture of bricks. It is also added to a range of mortars and lightweight aggregates. In addition to its use within the construction industry, steasint® is suitable as a component for greenroof construction and for soil enhancement in agriculture.
