Tutorials for the use of CEMDATA18 in GEMS

If you are a newcomer to GEMS and/or to Cemdata18, it is recommended to follow the examples and tutorials of the course on thermodynamic modelling of cement hydration, which took place in 2020 using GEMS 3.7 and introduced the new database version CEMDATA18:

  1. GEMS course introduction and cement chemistry

  2. Single calculation using hydration of C3A as an example

  3. Basic principle of process calculation

  4. Database implemented in GEMS

  5. Thermodynamic modelling of cement hydration

  6. Interaction with the environment
