FEATURES & SPECIFICATION

Fly ash is one of the naturally-occurring products from the coal combustion process and is a material that is nearly the same as volcanic ash.The most common use of fly ash is as a partial replacement for portland cement used in producing concrete. Fly ash concrete has increased strength and durability, which means it can handle greater loads, is more resilient and lasts longer. Fly ash concrete can withstand harsher service environments than straight portland cement concrete. Fly ash concrete costs less. Depending on what area of the country you are in, fly ash can be 20% to 60% less expensive than portland cement. In some cases, portland cement can be more than twice as expensive.  However, there have been few instances where fly ash was shipped long distances and sold for higher prices than local portland cement because the concrete durability requirements could only be met using fly ash.Fly ash has similar chemical composition to that of portland cement, shale and volcanic ash. Similarly to these materials, fly ash contains naturally occurring trace elements that are also found in rock and soils.
