Ash Development Association of Australia

The Ash Development Association of Australia was formed in 1991 by the producers and marketers of power station fly ash "to conduct research and technology transfer on behalf of members and to assist in developing market opportunities in the use of ash materials for all stakeholders."

The ADAA estimates that approximately 12 million tonnes of ash by-products are produced annually from Australian power stations. It states that approximately 85% of the power station ash used for various products is used as cement replacement "to enhance the properties of concrete and other building materials." The ADAA notes that while fly ash and bottom ash from Australian power stations have similar chemical compositions, their uses are quite different. Fly ash, which is a grey powder like cement, is used in a range of cement-based products. Bottom ash, which is coarser, "is used as a sand replacement, aggregate for lightweight blocks, a road-base component, for agricultural drainage mediums and as engineered bulk fill." The ADAA's website features photos of bottom ash being used as a base for a suburban bowling green as as backfill for a retaining wall.
