Properties of Czech deposited high temperature fly ash
Original language description
Fly ash, a by-product of coal combustion in coal-fired power plants, is a valuable raw material used in construction industry. At present, the combustion technology is gradually declining and the question arises as to whether it will be possible to use high temperature fly ash from stockpiles in the future. The aim of this work was to compare the properties of stockpiled high temperature fly ash (agglomerates) with fresh high temperature fly ash from the power plant Mělník (CZ). Laboratory tests were conducted to determine chemical and mineralogy composition, loss on ignition, changes in morphology, densities (particle, freely settled bulk and tapped), fineness, natural moisture content, standard consistency, setting times, soundness and strength activity index. Agglomerates from the surface layer of the stockpile Panský les (CZ) less than four months old had similar chemical properties as fresh high temperature fly ash. The behavior of agglomerates with cement slurries and mortars achieve the standard requirements for fly ash for concrete. Therefore, it would be possible to use the stockpiled high temperature fly ash for the same purposes as the fresh high temperature fly ash.
