· The to MJ/kg cement estimated for the electrochemical process does exceed the energy required for the conventional cement process in the average US kiln, which is MJ/kg . At a coal price of 61 per ton (for bituminous coal) ( 71 ), the energy cost for the conventional process is ∼28 per ton of cement, which is 25% of the average US cement selling price of 113 per metric ton ( 13 ).
How concrete is made
Concrete made with Portland cement is considered superior to that made with natural cement because it is stronger, more durable, and of more consistent quality. According to the American Society of Testing of Materials (ASTM), Portland cement is made by mixing calcareous (consisting mostly of calcium carbonate) material such as limestone with silica, alumina, and iron oxidecontaining materials.
