Topic

Cementitious materials show a rapid and complex evolution of pore water composition and mineral assemblage during hydration.

Thermodynamic equilibrium and mass balance calcula- tions are a valuable tool to understand the different processes in cementitious systems.

They can help to understand the consequences of different factors such as cement composition, hydration, leaching or temperature on the composition and the properties of a hydrated cementitious system on a chemical level.

Learning outcomes

– Understanding of the principles of thermodynamic equilibrium and mass balance calculations
– Basic knowledge on thermodynamic data
– Ability to calculate the hydrate composition of cementitious materials

Ability to create single systems and process files in GEMS to calculate:

– hydrate compositions of cementitious materials
– saturation indices
– chemical interactions of cementitious materials with the environment
