Because of its chemical properties, coal ash can be substituted for cement when making concrete. Encapsulating the coal ash into a solid state minimizes the risk of contaminants leaching into the surrounding soil, water and air. The resulting concrete is also generally used for non-residential infrastructure projects, which further reduces risks to human health.

Cement consumption is dependent on the time of year and prevalent weather conditions. Nearly two-thirds of U.S. cement consumption occurs in the six months between May and October. The seasonal nature of the industry can result in large swings in cement and clinker (unfinished raw material) inventories at cement plants over the course of a year.

By replacing the calciner in the cement plant with a calcium looping plant, it should be possible to capture 90% or more of the CO 2 relatively inexpensively. There are alternative set-ups such as placing the calcium looping plant in the preheater section so as to make the plant as efficient as possible.

Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.

Coal is still used in approximately 90% of cement plants globally to deliver the energy needed for the heat inside the kiln. Online coal analyzers using PGNAA technology are used to control the coal blend to a specific GCV in addition to the ash value of the coal as this adds raw materials to the process as well.
