Use of Power Plant Residues in the Production of Cement-Fiber Products

摘要

The cost of inorganic cementitious materials continues to rise as feedstocks, energy and transportation all become more expensive. As these costs rise, users of these materials are turning to lower cost materials as replacements for some or all of the cementitious components of their products. Power plant residues, mostly fly ash scrubber solids, but also bottom ash and cenospheres are a major source of these replacement materials. New technologies using these power plant residues are providing much higher quality in the finished materials, meaning that what was once a waste product stored in unsightly landfills is now a strong component of the construction industry.
