Mortar mixes comprising as a major part, Class F fly ash and fluidized bed combustion ash in amounts and proportions sufficient to reduce the negative effects of the presence of unburned carbon in the Class F fly ash and the presence of sulfate in the fluidized bed combustion ash and which mortar mixes also include, as a minor part, a cementitious material. The mortar produced by mixing the mortar mix with water can include a density reduction material and can be formed into support members for use in mines.
