Abstract

The article presents the results of research on the physico-mechanical properties of Cemented Paste Backfill mixtures (CPB) produced from low-calcium fly ash from a conventional boiler and from slag taken from a fluidized bed boiler with the addition of metallurgical cement in the amount of 5-15 wt%. Fly ash and slag were mixed in big quantities in various proportions. The tested mixtures with a constant concentration of solids to water of 62 wt% were characterized by a wide range of consistency: from paste to very liquid. The conducted research demonstrates that the best results were obtained for the mixtures with ash to slag ratio of 75:25 wt%.
