CFD Analysis of a Cement Calciner for a Cleaner Cement Production
Chemical Engineering Transactions, 2012 Cement calciners are pyroprocessing units found in modern cement plants. Inside of them occurs a strong endothermic reaction known as the calcination process, and the combustion of pulverized solid fuels. Controlling the mixing of limestone and pulverized fuel particles is of particular importance because it directly affects the energy consumption. The

3D Concrete Printing of Triply Periodic Minimum Surfaces for Enhanced Carbon Capture and Storage
Advanced Functional Materials, EarlyView.A 3D‐printable and carbon‐capturing concrete is developed by replacing cement with diatomaceous earth (DE), which enhances rheology, provides hierarchical porosity, and serves as a nucleation site for carbonation. Maximum absorption of 488.7 gCO2 kgcement−1 is achieved in 7 days, a 142% increase over conventional concrete, and the triply periodic ...

Oxygen combustion in cement production
Energy Procedia, 2009 AbstractThe cement industry faces a unique challenge in reducing greenhouse gas emissions owing to the large amount, 5% of global total, of process emissions originating from the calcination of limestone. Oxygen combustion is considered the most promising technological option as the energy penalty for capturing the CO2 is only associated with the fuel,

Leaching studies on cement-based products
Proceedings of the Institution of Civil Engineers - Construction Materials, 2006 Considering the increasing use of alternative fuels and raw materials in clinker manufacture for construction, the environmental behaviour of the resulting cement is a matter of particular concern. As the alternative fuels used in cement manufacture may contain elements not generally found in conventional fuels, this necessitates a study of the ...
