Fly ash works in tandem with cement in the production of concrete products Concrete containing fly ash is easier to work with because the tiny glassy beads create a lubricating effect that causes concrete to flow and pump better to fill forms more completely and to do it all using up to 10 percent less water

Fly ash is also recognized as an environmentally friendly material because it is a byproduct and has low embodied energy the measure of how much energy is consumed in producing and shipping a building contrast Portland cement has a very high embodied energy because its production

Cement type is not important Fly Ash – used as a workability agent to provide mixes that can flow great distances without segregation It also provides a slight cementing action Fly ash contents typically range from 200cy where limited flowability is necessary up to 1000cy where longrange flowability pumpability is necessary

Every ton of fly ash used in concrete in place of Portland cement reduces carbon dioxide CO2 emissions by roughly one ton Permanent Solution Conversion of coal ash previously stored in ponds or landfills into a sustainable construction material is a permanent solution to remove coal ash from the environment as it is excavated processed and
