摘要： Methods for increasing the amount of cenospheres in a fly ash sample are disclosed. The cenospheres are obtained in a dry state by using air as the “fluid” media for separation. In one version, the invention is a two step process, that is, screen by size followed by density separation such as in a fluidizing vertical column by density. In another version of the invention, the separation by density is followed by screening by size. Additional cycles can improve purity as defined by concentration of cenospheres.

摘要： A composition capable of setting to produce a building material is disclosed. The composition can include from 1% to 30% by weight of an activator, from 1% to 55% by weight of a pozzolan, such as fly ash; from 40% to 90% by weight of an aggregate; and liquid landfill leachate in a sufficient amount such that the composition sets to a building material having a compressive strength of at least 2 MPa, wherein all weight percentages are percent by weight of the total composition. The liquid landfill leachate replaces all or part of the tap water in a conventional composition for forming a building material. The liquid landfill leachate can be recovered after a liquid (typically water) percolates through a landfill and contacts at least one landfilled coal combustion product selected from fly ash, bottom ash, boiler slag, and flue gas desulfurization material. The building material can be a concrete, or a masonry unit.
