CO2 Capture by Cement Raw Meal

The cement industry is one of the major sources of CO2 emissions and is likely to contribute to further increases in the near future. The carbonate looping process has the potential to capture CO2 emissions from the cement industry, in which raw meal for cement production could be used as the sorbent. Cyclic experiments were carried out in a TGA apparatus using industrial cement raw meal and

Use of recycled aggregates for cement production

Moreover, cement manufacturers are familiar with alternative resources valorization (foundry sands, etc.) currently used to adjust the raw meal composition and substitute natural materials. The main hurdles to use recycled aggregates in cement manufacture are the sustainability of the RA supply chain, the cost of these materials and the regularity of the product characteristics.

Parametric Studies of Cement Production Processes

The raw materials are ground and mixed together in controlled proportions to form a homogeneous blend, termed as a raw meal or raw-mix, with the required chemical composition. Raw meal is then subjected to the continuous, high temperature operations in the pyroprocessing part of the plant, namely the rotary kiln system (RKS).
