Class C and F fly ashes were used in this research project. Currently, more than 50% of the concrete placed in the U.S. contains fly ash. Dosage rates vary depending on the type of fly ash and its reactivity level. Typically, Class F fly ash is used at dosages of 15% to 25% by mass of cementitious material and Class C fly ash at 15% to 40%.

A thermal power station is a power station in which heat energy is converted to electric power.In most places the turbine is steam-driven.Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.After it passes through the turbine the steam is condensed in a condenser and recycled to where it was heated. This is known as a Rankine cycle.
