Cement Production an overview ScienceDirect Topics

The production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity. Cement production accounts for about 5% of total anthropogenic emissions (IFC, 2017). Cement-based structures constitute the largest surface area of all man-made structures (Odigure, 2009).

2020-6-9  Abstract. Cement production is currently the largest single industrial emitter of CO 2, accounting for ∼8% (2.8 Gtons/y) of global CO 2 emissions. We show that the solid Ca(OH) 2 product readily decomposes and reacts with SiO 2 to form alite, the majority cementitious phase in Portland cement. Electrochemical calcination produces concentrated gas streams from which CO 2 may be
