Abstract: Fly ash, a coal combustion product once treated as waste and disposed in landfills, is used today in substructure and road works. The research of fly ash properties may solve the problems of treatment and intelligent use of this residual material. Using laboratory tests specimens, in this study the physical properties of pozzolanic coal fly ash, a bituminous coal waste of Iasi thermal power station, Romania, are investigated to analyze the composition of fly ashes, sometimes in comparison with the composition of those of Suceava thermal power station, Romania. The use of fly ash as a partial replacement for Portland cement is generally limited to the bituminous coal fly ash. Fly ash improves cement performance making it stronger, more durable, and more resistant to chemical attack. The recycling of fly ash has become an increasing concern in recent years and soil stabilization involves also the addition of fly ash to improve the engineering performance of a certain!
soil. The paper describes some benefits of fly ash use for our environment. The use of fly ash is accepted in recent years primarily due to saving cement, consuming industrial waste and making durable materials, especially due to the improvement in the quality stabilization of fly ash.
