Many of the by-products from coal combustion and flue gas desulfurization are cementitious, which suggests utilization in some settings replacing conventional cements. Information on the long-term stability of these materials in Nature can be obtaine

Four high-calcium coal combustion by-products (two pulverized coal fly ashes (PCFA), a flue gas desulfurization (FGD) residue, and an atmospheric fluidized bed combustion (AFBC) fly ash), were tested for engineering properties and ability to immobili
