Tutorials for the use of CEMDATA18 in GEMS

If you are a new comer 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 February 2018 at the University Bern, Switzerland using GEMS 3.3 and introduced the new database version CEMDATA18:

  1. Introduction into GEMS
  2. Single systems: C3A
  3. Process calculations: hydrated PC
  4. Thermodynamic database
    (5a detailed instruction for changes in the thermodynamic database)
  5. Solubility and speciation
  6. Saturation indices
    (+Tutorials 5-7)
  7. Alternative cements
  8. Effect of temperature
  9. Possible solutions for the tutorials
