Coal combustion fly ash - overview of applications and opportunities in the USA
- American Coal Ash Association, Alexandria, VA (United States)
The American Coal Ash Association, Inc. (ACAA) is an organization representing the coal combustion byproducts industry. Since 1968, the goal of ACAA has been to gain recognition and acceptance of coal fly ash as an engineering material on par with competing virgin, processed and manufactured materials by advancing uses that are technically sound, commercially competitive and environmentally safe. An annual survey of coal-burning electric utilities is conducted by ACAA to determine the quantities of coal fly ash produced and used in the USA. In 1993 approximately 43.4 million metric tonnes (47.8 million short tons) of coal fly ash were produced. Approximately twenty-two percent or 9.5 million metric tonnes (10.5 million short tons) was used while the remaining portion was deposited in disposal areas. The major markets for coal fly ash include cement and concrete products, structural fills, road base stabilization, flowable fills, mineral filler in asphalt, grit for snow and ice control, grouting, coal mining applications, and waste solidification and stabilization.
