Fly ash is a coal combustion product which comes from boilers used in the electrical generation process. The coal source is an important determinant of chemical composition, which categorises fly ash as Class F or Class C according to ASTM C 618 regulations (American Concrete Institute, 232.2R-2).
A cement plant consumes 3 to 6 GJ of fuel per tonne of clinker produced, depending on the raw materials and the process used. Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil.
Isidore C. Ezema, in Sustainable Construction Technologies, 2019. 9.3.1 Cement and Cement-Based Materials. The cement production process, for example, starts with mining of limestone, which is then crushed and ground to powder. It is then preheated to save energy before being transferred to the kiln, the heart of the process.
London coal gas production began in 1813 and by 1842 was producing 300,000 tons of coke a year, so coke was also readily available, and, being essentially a waste product, was cheaper than coal. Early cement plants used coal for drying slurry and for power generation, and coke for kiln burning. Per tonne of clinker produced, consumption was ...
