In fact the production of Ordinary Portland Cement "OPC" generates 842 kg CO2 /t of clinker [ [1], [2], [3], [4], [5] ]. In addition to its huge energy consumption, the cement industry uses large amounts of raw materials for cement production [ 6 ].
The results of SEM-EDS analysis showed that the ratio of the main oxides in the four phases was higher than the theoretical value. A similar result was found in Gineys's et al. research on clinker synthesized in the laboratory [23].The difference between the theoretical and experimental values could be due to the presence of minor elements in …

Classification Code (SCC) for portland cement plants with wet process kilns is 3-05-006, and the six-digit SCC for plants with dry process kilns is 3-05-007. Portland cement accounts for 95 percent of the hydraulic cement production in the United States. The balance of domestic cement production is primarily masonry cement. Both of these
About this report. The direct CO 2 intensity of cement production increased about 1.5% per year during 2015-2021. In contrast, 3% annual declines to 2030 are necessary to get on track with the Net Zero Emissions by 2050 Scenario. Sharper focus is needed in two key areas: reducing the clinker-to-cement ratio (including through greater uptake of ...
