In 1960, the Coal Committee for the United Nations Economic Committee for Europe requested a group of rapporteurs to undertaken work on the utilization of ash from coal fueling thermal power stations. This later became the Group of Experts on the Utilization of Ash. In 1959, out of a world production of 100 million tons of ash, only 2% was put to use, whereas in 1969, about 15% of a production of 200 million tons was used. In 1989, 562 million tons were produced, and 90.5 million tons were used. The main uses of coal ash have been in cement and concrete manufacture; in road construction and as filler on construction sites; in cellular concrete; and in lightweight aggregate and brick. Worldwide, in 1989, 27.7 million tons were used in cement and concrete manufacture, 23.6 million tons in road construction and as filler on construction sites, 2.8 million tons in cellular concrete, and 6.8 million tons in lightweight aggregate and bricks. This paper presents a worldwide survey of the production and utilization of coal ash from 1959 to 1989. The data were collected from various working papers of the US Group of Experts on the utilization of Ash and from two papers by O.E. Manz on the worldwide production and utilization of coal ash.
