“…and temperature are increased from 0.5-2 hours 1000 0 C-1150 0 C [25]. The porosity and water absorption of fly ash particles reported by [10] are lowest when the specimen are sintered at 975 0 C-1050 0 C. The maximum value of water absorption is obtained when the artificial aggregate is sintered at 1150 0 C and then decreased at a higher temperature.…”

Abstract:The waste materials from industrial are one of the concern issues in sustainable development. Recycle and reduce the waste material is one of the strategies to produce the better sustainable system. One of the methods is by using the waste materials to produce artificial aggregate. There are wide applications of artificial aggregate, for instance construction, agriculture, geotechnical fill, waste water, drainage and many more. Physical properties such as bulk density, specific gravity, unit weight, porosity and water absorption are important criteria. The performance of the artificial aggregate varies, depending on the application.

“…In general, the autoclaving aggregates have lower water absorption than steam curing because of the lower porosity. The agglomeration of class F fly ash aggregates through compression method that been sintered shown that the water absorption and porosity are decreased when the soaking timeand temperature are increased from 0.5-2 hours 10000C-11500C [25]. The porosity and water absorption of fly ash particles reported by [10] are lowest when the specimen is sintered at 9750C-10500C.…”

“…However, the density is decreased as the temperature is very high such as the aggregate is melting and bloating. The sintered artificial aggregate from class F fly ash obtained from different power plants also had different density [25].…”

“…Coal properties, combustion conditions and storage methods determine the mineralogy, chemistry and physical properties of fly ash. Therefore, fly ash derived from burning of different types of coal (e.g., anthracite, bituminous and lignite coal) has different chemical compositions and physical properties [4][5].…”

Separation of ultrafine particles from class F fly ashes

Abstract. In this study, ultrafine particles were recovered from Çatalağzı (CFA) and Sugözü (SFA) thermal power plant fly ashes using a specific hydraulic classification technology. Since fly ashes have a high tendency to be flocculated in water, settling experiments were first designed to determine the more effective dispersant and the optimum dosage. Two different types of the superplasticizers (SP) polymers based on sulphonate (NSF, Disal) and carboxylate (Glenium 7500) were used as the dispersing agents in these settling experiments. Hydraulic classification experiments were then conducted to separate ultrafine fractions from the fly ash samples on the basis of the settling experiments. According to the settling experiments, better results were achieved with the use of Disal for both CFA and SFA. The classification experiments showed that the overflow products with average particle sizes of 5.2 μm for CFA and 4.4 μm for SFA were separated from the respective as-received samples with acceptable yields and high enough recoveries of -5 μm (ultrafine) particles. Overall results pointed out that the hydraulic classification technology used provided promising results in the ultrafine particle separations from the fly ash samples.
