Fly Ash Sulfur Concrete

Two waste products, fly ash and elemental sulfur, can be combined with a modifying agent to produce a potentially useful construction material, fly ash sulfur concrete (FASC). Production of the material in the laboratory is simple and direct. Strength characteristics of FASC are affected by the amounts of the ingredients present and the unit weight of the mixture. Compared with a conventional crushed stone aggregate, FASC is a viable highway pavement base course material with respect to predicted theoretical pavement performance. Definitive assessments of the utility of FASC await reliable cost and durability data and construction experience. From perspectives of both environmental protection and energy conservation, waste products (either singly or in combination with other wastes or stabilizing agents, or both) can and should be considered as candidate construction materials.
