The use of fly ash as supplementary cementitious material (SCM) has been proven to be effective at maintaining the sustainability of concrete. Since fly ash is the combustion byproduct of coalfired power generating plants it s readily available without taxing natural resources or the energy it takes to mine and manufacture those resources.
Sturgis used data from the EPA s Toxics Release Inventory (TRI) for 2006 the most recent year available. The use of fly ash in cement kilns in the has grown from about 1 million tons in 2001 to more than 4 million tons in 2006. Mercury and other metals in fly ash are transformed into vapor and released out of the kiln s smokestack.
