Cement Plants: Coke
Cement Plants: Coke. Coal-derived coke was the fuel used in most static kilns and so was the dominant fuel in the cement industry in the nineteenth century. Coal could not be used in static kilns in which the fuel is fed in with the raw material, mainly because, during the gradual heat-up of the charge, the fuel's volatiles are lost without ...

Coal utilization in the cement and concrete industries
Abstract. The utilization of coal in the cement and concrete industries takes three basic forms: (1) as a fuel in the production of cement clinker; (2) ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds; (3) ash produced by burning coal in power stations is used as a mineral additive in concrete ...

In 1824, Joseph Aspdin, a Leeds builder discovered what we call "Portland cement". He prepared it by calcining finely ground limestone, mixing it with finely divided clay and calcining the mixture in a kiln until all the carbon dioxide evaporated. Following this, the mixture was finely ground and used as cement.
