And depending on how that cement is produced, this can increase the material's environmental impact. This is in part because when calcium carbonate is fired in a kiln to produce conventional cement, a chemical reaction occurs that produces carbon dioxide (CO 2). Another source of cement's CO 2 emissions come from heating cement …
