Their use as being a small-Strength choice to Portland cement has been pioneered in China, where a number of million tonnes per annum are made.[46][47] Electrical power demands are decreased because of the lower kiln temperatures expected for reaction, and also the decrease degree of limestone (which need to be endothermically decarbonated) in the combination.
