| Abstract Scope |
A considerable reduction of CO2 emissions in the production of building materials is mandatory to fight climate change. To reach this goal, CO2 must be limited in the production of clinker, the active component in any type of cement. Potential levers are the clinker chemistry (raw materials, chemical composition) and the process conditions (burning temperature, fuels).
Multicomponent phase diagrams and thermodynamic equilibrium calculations using a reliable Gibbs energy database are fundamental tools to reach this goal. They form the basis for the development of models to predict the clinker chemistry from the chemical composition and to model the full clinkering process including heat and mass transfer. In this contribution, we will highlight some key thermodynamic results and discuss their impact on the reduction of the specific embodied CO2 in the final cement and concrete. |
