The recycled cement is meant to be used to interchange section or each of the lime Employed in steelmaking, resulting in a slag-like substance that is analogous in mineralogy to Portland cement, doing away with almost all of the linked carbon emissions.[fifty]

"Organic" cements corresponding to particular cements in the pre-Portland period, are made by burning argillaceous limestones at average temperatures. The extent of clay factors in the limestone (all around thirty–35%) is these kinds of that giant quantities of belite (the low-early toughness, significant-late toughness mineral in Portland cement) are fashioned without the development of abnormal quantities of free of charge lime. As with any normal substance, this kind of cements have really variable properties.

Their use for a low-Electricity substitute to Portland cement continues to be pioneered in China, where quite a few million tonnes a year are produced.[forty six][forty seven] Power needs are reduce due to lower kiln temperatures demanded for reaction, and also the reduced amount of limestone (which should be endothermically decarbonated) in the combo. Also, the reduced limestone written content and decrease fuel consumption contributes to a CO2 emission all around 50 percent that connected with Portland clinker. Having said that, SO2 emissions are generally appreciably greater.
