FLY ASH CONCRETE - WHAT ARE THE REASONS FOR

More than 12 million tons of coal fly ash are used in concrete products each year. The use of fly ash, a recovered resource, reduces the depletion of natural resources. It also reduces the energy intensive manufacturing of portland cement. This reduction in energy leads to less emissions of greenhouse gases.
