Albrecht Schall, VDZ, discusses the ‘Zwolf’ and the role of maintenance in ensuring that cement kilns operate effectively. Published in: World Cement (2021) 12, 35-38
The use of calcined clays as a main component of cement or as an additive to concrete is becoming increasingly important and of interest from an economic and ecological point of view. Standards such as the European Cement Standard EN 197 already today provide for the use of calcined clays (as natural tempered pozzolan) as a main component of cement. Depending on their chemical and mineralogical composition, the clays used must in principal be heated to temperatures of over 600 °C in order to achieve their pozzolanic potential. VDZ has developed a new process for this purpose, which we are pleased to present to you in the attached document.

The capture of CO₂ and its subsequent use and storage are essential elements of the cement industry's decarbonisation strategy. The capture of CO₂ from the flue gas is energy-intensive and complex. It can be carried out more easily and efficiently by maximising the CO₂ concentration in the flue gas. The separation of the calcination of the limestone in the raw meal from the burning process to produce clinker phases simplifies the accumulation of CO₂ in the flue gas significantly.
