Cement production phases

Aug 20, 2015 Domestic cement production has been increasing steadily, from 66.4 million tons in 2010 to about 80.5 million tons of Portland cement in 2014 according to the U.S. Geological Survey 2015 Cement Mineral Commodity Summary. The overall value of sales of cement was about $8.9 billion, most of which was used to make an estimated $48 billion worth of

    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)

    The cement phase can be preblended or mixer blended, although the former is limited to a maximum of 55% of cementitious content in EN 206 and thus just within the HVFA range. Given the low free water contents and water/cement ratio used with HVFA, super plasticizing chemical admixtures are used to achieve the required workability
