Abstract:Landfilled fly ash was sampled from the Jim Bridger and Dave Johnson power plants in Wyoming and the Nucla station in Colorado. The chemical and physical properties of these LFAs in their as-received condition were evaluated, and those not conforming to ASTM C618 (the international standard for fly ash used in concrete) requirements underwent mechanical and thermal beneficiation, which involved grinding in a ball mill and exposure to high temperatures in a muffle furnace. A comprehensive set of experiments was conducted to assess the performance of mortars that combine ordinary Portland cement (OPC) and beneficiated LFA in terms of physical and chemical properties, reactivity, compressive strength, electrical resistivity, resistance to alkali-silica reaction-induced expansion, water absorption, and chloride permeation.
