  • Case study - High volume fly ash for the 2 Folsom project

    High Volume Fly Ash (HVFA) concrete was successfully used as the cornerstone of this project’s sustainability program. HVFA concrete was aggressively pursued because of its environmental benefits. When fly ash is used in place of cement, energy and landfill space is conserved and greenhouse gas emissions are reduced. During this HVFA project, roughly 2,800 tons of CO2 emissions were ...

  • Recycling of Fly Ash Produced in Combustion of Brown Coal with Increased Germanium Content

    A possibility of utilization of fly ash resulting from combustion of Czech brown coal with increased germanium content in a circulation fluidised bed combuster is examined in this study to recover germanium chloride. The laboratory measurement presented in this paper was focused on three aspects: obtaining raw germanium chloride by its direct distillation from the suspension of fly ash and HCl; ...


  • Lead sorption performance on active silica derived from fly ash

    The object of this study was to estimate the sorption property of active silica derived from fly ash after separation of silica and aluminum. The specific surface area of active silica enlarged to 115 m2/g was compared with the original fly ash (4 m2/g). Field emission scanning electron microscopy displayed the active silica, which looked like a honeycomb or curly layer with many ...

  • Determination of Ammonium in Fly-Ash using the Distillation Unit KjelFlex K-360

    To reduce the emissions from ammonia to the environment the content of ammonium in fly-ash is determined. Depending on the ammonium content it is decided how to dispose the fly-ash or if it can be used as additive, e.g. in concrete. An easy and reliable method for the determination of ammonium in fly-ash is introduced in this article. The distillation and boric acid titration was performed with ...

  • Case study - Fly ash for stone matrix asphalt in Oregon

    Stone Matrix Asphalt (SMA) is the latest low wear, long life asphalt pavement. It has a proven track record in Europe and is growing in popularity with State Department of Transportations across the country. Georgia alone placed over two million tons of SMA on its roads last year. The Oregon DOT is the latest to adopt SMA and is using it as a high durability asphalt wearing surface on 10 miles of ...

  • Combined load and leachant pH effects on contaminant release from fly ash

    Several studies have been performed recently on the suitability of particulate waste materials as substitute aggregate in load bearing and geoenvironmental structures. To investigate the long-term performance and durability of these recycled materials, the coupled effects of the interacting fluid chemistry and applied load are herein analysed experimentally. The leachability of heavy metals ...

  • Impact of fly–ash–amended soil on growth and yield of crop plants

    Fly Ash (FA), a waste product of thermal power stations, has great potential for use in agriculture, because it contains almost all macro as well as micronutrients. In view of the potential disposal problem of FA, this investigation was carried out to search an economical and eco–friendly solution of its disposal by using it as nutrient source in agriculture for growth of crop plants. FA ...

  • Removal of carbamazepine from aqueous solution by adsorption on fly ash-amended soil

    Carbamazepine (CBZ), nonbiodegradable pharmaceutical residue, has become an emerging pollutant in several aquatic environments. The effectiveness of the mixture of soil and fly ash (FA) in adsorbing CBZ from aqueous solution has been studied as well as agitation time, FA content, initial CBZ concentration and desorption as a function of FA content. The adsorption kinetics fits a hyperbolic or ...

  • An immobilisation mechanism for lead in fly ash subjected to mechanochemical treatment

    Mechanochemical (MC) processes immobilise heavy metals in fly ash, a desirable outcome because recycled fly ash is commonly used in the synthesis of inorganic materials. We investigate the extent of immobilisation and the mechanism of lead (Pb) leaching during MC treatment of fly ash, using lead oxide (PbO) and lead dichloride (PbCl2) as model compounds. MC treatment of the ...
