Thermodynamic modelling of cement chemistry at high temperature

The prediction of the likely future state of cementitious materials has been the focus of research for many decades and has expanded to match the availability of computational power and of codes and data.The field has traditionally been divided into two activities and even communities; high and low temperature methods.By tradition, each community has favoured its own models, codes and data but recent developments are leaving this boundary less distinct than in the past.To compound this, is the wider adoption of methods complementary to thermodynamics, which makes modelling high temperature cement chemistry an exciting area in which to conduct research.What follows, is a very personal view of the major advances in modelling cement chemistry at high temperatures, the needs and drivers to model development and an equally personal speculation about areas of fruitful research and development in the foreseeable future.
