The synthetic zeolites were synthesized in the hydrothermal reactions of fly ash from hard coal combustion with sodium hydroxide (NaOH) [51], [52], [53].Fly ash for zeolite synthesis was supplied by the Heat and Power Generating Plant in Poland.
اقرأ المزيدA multivariate regression model was developed to predict UCS of tailings amended with fly ash as a function of (1) tailings water content, (2) water-to-binder ratio, and (3) CaO-to-SiO 2 ratio of fly ash. The model was developed using data from synthetic tailings specimens and validated via tests on natural tailings and data compiled from ...
